How to start a new collection of object

Hello,

I am looking for how to create custom objects managed by users on EasySocial.
These objects should have their own display page, and should be editable by 1 member of the network (or several if possible).
The object should have a photo (banner + profile), some fields like name, location, etc.

I am wondering how to start that development and how to structure it to best fit easysocial code, anybody could help?

Thanks
