There are several suggestions .... not if I have to put together a post for each or put everything here ... so here they go
Auto mail: To greet a user on his birthday
Auto mail: Alert you BIRTHDAYS users in your city or country.
Auto mail: Alert new user registration in my area
Private photos: ... that can be seen only if given permission, no matter whether it is friend or not. Currently the friends can view private photos and do not always want it to be so.
Admin: From the Admin see who is online.
Admin: From the admin to activate the e-mails are not confirmed.
Improve a little part of the account settings ... the designer must have missed that day!
I am here to ... to select more than one option
Favorites system .. to add users favorites without having to make friends.
Special gifts. Which they can only be sent by those who have super power.
Mail domain block. You can not register anyone with a particular domain such firstname.lastname@example.org
More info on the users table .. example.. if online, credits, if the mail is confirmed, has few pictures, etc.
Photo Approval. monitor and approve or not all photos .. or just those that are marked private
Edit photos from the admin: So as you can delete a photo from a user, I'd be good for a picture "uncomfortable" can be made private from the admin
Please .. a referral system ... that by inviting 100 users and these are registered, the user who made the invitation earn x amount of credits or membership days ... and of course, you see a table in the admin users who made few invitations and registration is completed .... I said but I say again lol
It's all for now .. lol hope you understand, but the blame lies google translator. (Not sure if you can put things in Spanish here)
