So, What I thought was:
To create a few classical projects to attract some spriters from outside, some exemples are The old School Dexs; Revampdex, Devampdex, and Scratchdex. To attract some new member we could create some kind of 'school' to teach them the basics, this really attracts some new members but it's kinda hard to keep them interested, so if we want it to work we really gotta think how we'll do it.
Another project some guys tried out for a while in my old community was a Role Playing Game based on spriting, this one was really fun and we could make some partnership with the RPG section (there's one on the Forum, right?). I may try to explain, in a separate post, how it used to work if it interests you guys. I don't really remember with all the details tho.
Once we get enough members again we could bring some contests back, and create a few new ones. GWSC, GMSC, GAC (General Arts Contest). Each one of them with a different style and system.
Sorry if my English ain't that good. If something sounds weird please warn me, so I'll try to explain it better.
Made a new post instead of editing tho. Seemed easier.
