i second this - sometimes you'd like to add something afterwards.

and i would appreciate a lot if there was (or did i miss the feature??) like a subscription for following comments too, one you could switch on/off. it happened that i had asked a question to a particular item, and not knowing when the artist replied, i had to bookmark the page and peek every now & again to see if the answer was there. not only does this generate a totally buggy number of viewings, but i might just forget about one thread..
