I pop on Subeta to look at pet designs, but I never really clicked because there are so many angsty teens flaming you for no reason and at that point I was rather depressed anyway, so I didn't need that.
Then I found Aywas. Great community. Lots of older people. We still have drama but it bubbles under the surface. As long as you're not a giant pain in the anus you'll make loads of friends.
I use Neopets, Felisfire and Aywas. Aywas more, but I check the others.
