Heh, I was just wondering 'cause it made me look like an idiot when I made a mistake and posted the same thread twice!
I'm kinda split on the issue actually. I've never liked editing my posts more than about an hour after I made it... kinda like once I say something (and have made it somewhat gramatically correct), I stand by it. Deleting posts (and threads) is kinda the same. It does bug me a bit when someone deletes their opinion or outburst to cover their own ass.
Still, sometimes mistakes happen. I guess as long as mods have the ability to delete posts and threads, then someone could simply ask a mod to do it for them (to correct a mistake). I think it's probably a good thing, but I'm curious to hear other people's opinions as well.
BTW, could someone delete the redundant "What type of woman" thread in the LL?
