A huge problem here is the 'for sale'/'for trade' posts. A guy should be able to post something for sale or trade in the appropriate sub forum and not get attacked and have his post turned upside down by a bunch of guys that don't agree with the price or details of the trade. Most of the time this is where the problems and attacks start. If we are going to continue to allow people to post stuff for sale or trade here we should look at a way for these posts to be 'locked' from outside comments by the OP. Most of these posts are not asking for comments or opinions just simply offering an item for sale or trade. It always turns negative somewhere along the line and then usually gets ugly... It would get rid of the negative and the positive (GLWS, wish I was closer, etc.) noise which is all worthless to the OP anyway.
just my 2 cents.
