My main activity still is on flickr, this is my backup account. I keep in touch with some fugitives from flickr here and post my pictures via a greasemonkey script.
I don't post my pictures to any groups here on ipernity and don't think I will be due to lack of time. My membership in groups is just limited on some conversation for meetups e.g.
I try to comment and answer comments as much as I can but as I said - flickr's first...
Thanks for your interest in my pictures and have a nice stay on my site!
