i would say 2 years … believe me buddy if they did with 2 years they would free a lot of space … specially from some guys with 3K+ portfolios … besides , i think that authors should also try o regulate themselves somehow and get the job done alone … i did for instance … but some guys just think about overflowing the place, period … they do not care about creating quality as they do not bother taking out unsold things even if this is giving a hard time to a whole lot fo guys , since this is the reason for lots of contents to be hard rejected in a more selective way …
