I honestly don't think you should regret starting the thread Pamie.... it was started as you say with a view to fun, but it also afforded an opportunity for those who feel they have valid viewpoints on the subject and wanted to air them. As you said many very good points have been put forward, which might not have been had the thread not been started.
I have always applauded this forum more than any other for the willingness always to support another's views even if they don't follow the usual path, it's why I come back time after time. It's threads like this that make the forum work for me. Passions have been intense in this one, but no one has started a flaming session.
A lot more Stargate discussions should be so sensible!
I too await Season 6 to see what the new guy will do and how they will assimilate him.
