G@Gers cannot edit or delete their own posts because ever-changing posts would simply cause too much confusion for those trying to read them and keep up. It could also even completely change the tone/content of a post that people have already responded to, which again, is very counter-productive and messy. There are also Xper points involved with every post and every removal, making it even more difficult to manage thoroughly. Everyone can always add updates to their questions, and comments to their answers... if they need to correct anything. As always, we encourage you guys to write your posts carefully and make sure not to post anything you'll later regret.
