The name of the game is due diligence. If somebody showed up to your front door and said he had parts you were looking for, would you give him some cash and tell him to come back with the parts? No. If somebody showed up at your door and said he had parts you were looking for, would you turn him away just because he drove a Dodge? No. I use a gmail account. I like it just fine. If someone doesn't want to deal with me because of my email account, well, I guess I'll just keep my money in my account. Gmail isn't a flag. No posts, no history, no participation, no knowledge, no pictures, no bank account... those are flags.
