I come here from other forums where I'm used to being able to edit posts forever. Here, posts freeze after some time period, unclear, a few hours apparently. I'd like that to be increased or removed. I like to revise my posts, not to change their meaning, but I often add more information and sometimes remove inaccurate things. It's just my style, but it's frustrating when you realize you said something you'd rather say differently, and then find that you can't edit it anymore.
