Not a bad idea. You should know a little from the posts who you are inviting. I mean if Iceman is coming over you know he is harmless and will talk your ear off. WV is a pretty good guy, you can tell. TimeTOPay is someone your wife would be right about and would want to keep far away. Get it? You know via the posts who you are inviting over and have a pretty good idea. You just cannot invite the world without knowing who is coming over. Show good judgement like your wife did with the $700 Christmas tree. Smile.
