You come to this news group with your trash talk everyday and you have a problem when I poke sticks at the latest troll to visit the news group. Well thats just to bad. I don't care what you think. You never contribute information here. You are a member in very poor standing. As long as I'm not as obnoxious and strange as you I'll be OK. When is the last time you made an on topic post? A few months ago last year? Maybe one or two at most. Do everyone that reads the news group a big favor and go someplace else or grow up. Take your pick. -- Telamon Ventura, California |
