No harm, no foul Tweed. I can understand your reasons for doing so. There is nothing wrong with having fantasies, and I can see why you would not have wanted to admitted to being only 12 when you first joined the forum. You're quite intelligent for your age, and I think you'll be a lot more successful 24 years from now than the 37-year old "you" was.
Ditto, I'm not really bothered about it. And I can understand his decision. When Tweed joined the forum we didn't have users like Ilikeverin, HockeyDude, PBrunsel, MAS, etc. who basically proved that under-16s can be perfectly capable of holding an intelligent political discussion, so he probably would have met a lot more prejudice here.
At the end of the day internet discussion forums are all about ideas and viewpoints, and issues like a poster's age shouldn't really matter. Tweed contributed a lot to this forum so I don't see any reason to be mad at him; if anything I'm impressed that he had us fooled for such a long time.
