Handle a situation with maturity.
The fact that they didn't accept you, sure they had a reason behind it, maybe you're not ready for it yet.
You just have to learn from the past and make this failure a reason to keep moving forward and not giving up on it.
We all began the same way as you. We've been rejected plenty of times and approved many times as well.
You just need patience, more improvements... That's all.
Well, If nothing will change your mind then good luck finding another community.
