I dunno if this was brought up before,
I think a good idea would be to create a favourites watch list for the designers section. ( kind of like deviantart if you know what i mean )
so that you can add designers to your watch list, and it will update you in your profile, or by email, whenever they put up a new poster. because after sifting through like, how many is it... 40 000 designers? i dont know if i can remember all the ones i liked :P hah.
