I don't know why people insinst on proposing subscriptions as though they would become mandatory... which they won't at all. it has been made very clear multiple times during this thread.
other features as:
capping the count of watches possible: I didn't know there was one. either way, it's nonsense. what would be accomplished through it?
front-pager exposure of latest submissions for subscibers only: and what about talented amateurs? besides, what looks like utter crap can mean the highlight of the year to the enxt one. thus: schnickschnack.
there were other nonsense which would make me pack my things and go very fast even though I could afford a subscription: because it would be very unfair to other artists who couldn't afford it. and I can imagine a lot of established ones who wouldn't stand in for it out of principle.
I'm not sure what I should do with a poll system... I put up a journal entry, ask my questions and wait for the answers to trickle in.
I would have a couple suggestions for features for all that would need some work, though.
first, maybe an additional submission theme might be helpful; "Fetish clothing/tame" res. "adult". since I and a couple other artists would use that one a lot.

and in my opinion the species list would need a work-over. and maybe add "pea" to the "Apple". XD
making the use of tags mandatory would help with search functions greatly, I can imagine. not everyone feels inclined to use them. if the search could include the custom tags, it would be awesome, as long as they would be found with 'near hits', too. but that would probably be too much anyway, so there.
personally, I could use a working 'delete' button for my received PMs. after one screwing-over in the distant past I amassed six or seven pages of PMs I don't need anymore.

also, being able to edit one's own replies (and submission comments more easily), as soemone asked before, would be icing on the cake, if only to wipe out misstypings or unsafe wordings made late at night, found the second you hit 'add reply?'. or you could fill that empty reply box you just sent off with a healthy "Duh!"... XD
