For Sale comments.

I would like to suggest that you should not be allowed to comment on users "For Sale" threads unless you are interested in the actual sale. It clears up the clutter and the posts are pretty much "Good Luck", "Nice", "I wish I had the money". Its nice to encourage somebody on their design or whatever but honestly it is pointless and it clutters up the thread.

But if somebody is trying to sell their services, someone that has worked with them before should be able to comment and recommend them to other users, thats a good thing.

What do you think?
