Good point........... Those posts where the member just joined that day, and you can see the gun being posted at 3:30am scare me for some strange reason.I think the most important thing you can use to identify someone you do want to do business with is how they communicate via text or IM.
High or low post numbers, someone who speaks in coherent sentences offering a reasonable price and saying something like, "hey I can escape the office at lunch and meet you at Academy at 12:15 or right after work" is probably a hundred times more likely to show up than someone shopping the classifieds Wednesday night saying "I can probably get over there Friday or Saturday". They'll often change their mind by Thursday afternoon when they sober up.
There are a few members here I'd absolutely hold something for if asked. They of course do have high post counts and have been around for years.
