adidas: I guess I'll try to forget about posting them in the future?...
my opinion? yes. unless they start posting different galleries, anything there can also be found at the "plugin" galleries but with better pics and without the annoyance of registering/logging in.
so if you ever see something at teen-beauty, just go to
http://hosted.met-art.com/plugin/ and post the gallery from there instead, unless a "hosted.met-art.com/generated" gallery has already been posted (see this post for an explanation).
