Way back when, I was a pretty active participant in a photo site called BetterPhoto. We're talking 2003-2009 kind of "way back". A bit of a long story why I stopped, and doesn't really matter. In early 2015, I started posting to 365project, and I'm still pretty active there.
Anyway, I recently saw (through Facebook), that one of the folks I met through BP (BetterPhoto) has been posting there again so I thought I'd check it out. Turns out they remembered me, and that quite a few of my old photos are still there. It says I have 886 photos, and I can see 215... but only display Most aren't displayed (since paid membership expired). So I decided reactivate my account (as the free version), and poke around for a few days. Maybe even step up to a paid account. We'll see. I expect I'll stay w/ 365project, though, I've enjoyed that site.
Anyway, always looking for new communities, If you have places you prefer, drop a link in the comments!
Here's a couple from the 215 that apparently received "All Time Editor's Pick" designation, sometime after I left...
