Well I have a
gaia
roliana
Soliaonline
Menewsha
Zantarni
and Ernya but the only one I use now is Ernya. I felt that I didn't have enough time to go on these websites so I narrowed it down to one. Occasionally I do go on those accounts to talk to old friends of mine but I don't think that I would become addicted to theses sites like I was in high school.
I'm on here, Roliana, and Solia. I used to be on Menewsha and was a mod for a while, but the other mods there at that point were assholes, so I left. I don't know how it is there now, as this was years ago, but I doubt I could ever return there.
I'm really only active on here, Subeta and Crysandrea. But I am on a lot of avatar sites that I just haven't been to regularly in a long time. Gaia was my first avatar site and I go there once in a while. Neopets was my first pet site and I rarely go there anymore either. I have Menewsha, Roliana, Zantarni, Solia, Kinsaki, Midorea and others that I can't remember right now.
I think I have an account on a lot of different avatar sites (gaia, subeta, pupee, menshwa?, tinierme, and more that I can't remember). But I'm really active on any of them except for occasionally here and on subeta.
I used to have a Gaia account but I no longer go there. Don't have any other accounts on avatar sites besides this one and Gaia. There's just too many to really do much with them. I try to stay on or one or two at the most.
I've been on Gaia for 6 years. I also have a Roliana account but it's not that great. Stardoll and TinierMe are ok but I wish they had more for the people who want to play for free.
I have about 6 other avatar sites xD
Three of them I get on often just like this site, but the others I tend to forget the name and only check up at random times.
