I actually have a few, they have been in my mind for a while. Maybe you could possibly add an objectives section on this site? kinda like trophies, but instead of just winning them for the satisfaction, you could do objectives that are linked to ovipets to where if you did a certain thing (a.k.a mission/objective/quest) and possibly get a chance to win something from it? Like pets, credits, etc.
Also, this may be fun for everyone and could possibly bring people in more. I think a tab just for raffles would be great, or giveaways- basically the same thing. Like, you could throw some on here and announce a prize, and after a certain time and after people did the certain things wanted of them to be able to join, they could get a chance to win a given prize from admin(s). Almost exactly like raffles/giveaways on ovipets- but instead its on OviExtra.
I don't know, these may be a bit out of reach? I just think they would be a cool addition to the site. What do you think, Mattias?
