I would hate to see people selling stuff but only to say members with 500 post or above if that's what your saying. If other with less posts got in first it could get messy. I know I've missed stuff that other have got to first but there is always something that comes along. Plus this IDE could not be built into the forum if that makes sense. Only locking non members out of seeing the for sale boards
No nothing that high thinking the same limit as selling ie 20, stops the trolls who only come here to get a steal, but the locking of sale boards who have the same effect.
