I let my Core membership run out this year. I originally got it just to change my username. Didn't even think about how useful the stats are, but honestly, I haven't been using dA much lately anyway. So, not sure if I'll end up re-upping later on or not. The biggest drawback to me is the automatic renewal. I don't like that one bit. Doesn't matter that I could cancel automatic renewal later — they know people forget to cancel things. I ain't mad about it though.
Anyway, lots going on, working on some crochet pieces now, will have to get some more drawing and stuff done later on.
