Thats nice, thanks to the guys who finally heared to your Community and thanks to Shark (and all other people) for his try to make a better Server, im not kind of mad at you or anything because u just tryed to get your Server full, it was just that you didnt discussed it with your own community that made me a bit sad/angry.
Since its going over to Classic, there will be alot of Players who will comeback (me included) and you have a good basic-membership i would say. The Problem of the old Classic-Mod was:
1. The Maps were so old, that i already knew every Pixel on that Map and it got kind of boring, since no one did something People lost the hope that there will be just any variation.
2. On alot of Maps were still bugged Camptimers, so alot of Player basically abused and Camped there for 2-3 Kills moved maybe for a few secs to another spot and then you saw them there again camping for another kills (So they could say in the case they get slayed: "i didnt camped wtf".
3. I saw on some other Servers now (Rubix you aswell at the Polska Server), that they added a Level-Plugin so they got upgraded Weapons (Like Golden Deagle, M4, AK47 etc.)depending on their Level, just visually upgraded ofc. Maybe this could be another option aswell for Ambro to just keep new Players there.
4. Im not sure if its possible, but maybe u can add the Mic-function aswell, like in DR, because sometimes its pretty funny to talk to each other and for other players possibly aswell. If not there is still /mute
Just a few suggestions though, maybe they next days there will be some other from my side aswell.
Well yes all i tried was to make an active server but the wrong part from my side was that it should have be done with the suggestions of the head admin and the surfers of our community in the first place so it would result to a server that we all like.
Now lets focus on making a nice classic surf. 
I like the suggestion of level-plugin and about mic i dont see that it might cause any problem since theres /mute option aswell.
And about maps we added to surf gungame a lot of different maps than we had in classic so check these maps too guys and if you like some of them we can keep them.
Here is the current list of surf gungame:
1 : surf_nice_fly_4
2 : surf_srventer
3: surf_iceday
4 : surf_ag-final
5 : surf_r_nd_b1
6 : surf_psycho_b2
7 : surf_ny_final_v2
8 : surf_paris_final
9 : surf_highspeed
10 : surf_highspeed_2
11 : surf_machine2 (disabled was crashing the server)
12 : surf_iceday2
13 : surf_impulse
14 : surf_ski_ths3
15 : surf_twisted
16 : surf_green-reloaded
17 : surf_ski_5_final
18 : surf_cybol
19 : surf_sand
20 : surf_lagoon
21 : surf_sand_2
22 : surf_the_flow
Honestly, i havent seen every Map yet, but there are ofc alot of Maps u can keep on. And actually this is something all should decide together. I personally think, Paris Map should get removed, since its too small (and actually not enough players could play on it, like sometimes i saw tons of People just staying in Spec, but its pretty important just to ask the Players themself what they think. And not only just in the Forums, just ask those guys who join the Server randomly, and may want to stay at Ambro, when they see that Admins/Players are caring about their opinions, im sure they will stay and come more often.
Another thing that i wanted to add: is just the attitude/fairness, since sometimes we have alot of Players (i was sometimes also like that). I got the feeling that, when your Friend is an Admin u can allow urself everything. Example:
Player X insults someone (is not known at all in the Server)=> gets kicked
Player Y insults someone (but is a friend of an Admin) => gets no kick
I know its hard for everyone, because we cant do everything perfect, but we should try our best to be fair to everyone and sometimes just not to overreact (even its really really really really hard sometimes :d)
Compared to other Surf Servers, and i have seen a lot now, Ambrosia was always the one with the highest skill level, and this was something that made me kind of feel like at Home here. I saw so many Players, who didnt even know how to Surf in the beginning and in the end they were just at a pretty highlevel and alot of times i saw them at the Top15 (Even Top 15 in the end was just camping like hell

).
Also you can keep staying at DM, for some Maps (like Surf_Ski_2, Cybol etc., as the old ones) because it was sometimes, just cool to chill off a bit, with alot of Players + Admins (who keep an eye on Surf, that its gonna stay clean). Because alot of other Server (especially DM Surf) have like 0 Admins. If u have no one who trys to keep everything clean, people will get mad and start fighting eachother which leads to a rage/-quit. So sometimes a little DM Map to chill off a bit, but still "clean" is also a nice thing though.
