I don't mind the fact. I mind not being notified though, and so should the mods, because they had to check my submission twice. It could easily have been three or nine times if I hadn't been clever enough to ask.
They should just add a statement that all submissions are not selected for the gallery on the submission page... It's not like it requires any major restructure of the website to do that.
I'll just hold my head high, and keep creating more of the sometimes ehm... unusual ... style of things I do. It's not a popularity contest... Or wait... It's a community... Never mind, I'll just ignore that fact and hope my creations appeal to those with a slightly more esoteric taste.
