There should be functionality to allow editing other posts in bumped threads and not just the first post. Sometimes it becomes confusing editing the first post with other stuff you've posted in the thread. Just a thought.
I would love to find out if there is an option to edit my own thread the next day. I found several misspellings that I made yesterday. I was sleepy, I guess, I am a little bit disappointed with my posts now. I wish I could make some small changes, correct couple words etc...
Most browsers now highlight misspelt words. However, a browser might be set to another language, so something like http://www.spellcheck.net/ can always be used before posting instead.
My suggestion was not about misspelled words. Do you really think I care about typos? My ego is not that sensitive lol. This is about sales threads where sometimes you will edit the first post and other posts in the thread no longer make sense.
The idea in principle is a decent idea... the problem though is that you also have to think about how people can use it outside the scope of what it was designed for. We get all sorts of idiotic requests from people (like users with 10,000+ posts from the last 8 years asking their account be deleted and all posts removed)... A big part of why we don't allow it is threads they participated in start making no sense at all when you remove their posts from it. So you take something like that... say there is a big thread with thousands of posts and someone decides to be obnoxious and change their hundred existing posts in that thread to something like, "please delete". Then we start having problems of not just threads making little sense, but you also have to deal with trying to monitor when that happens and cleaning them up (either restoring the posts or actually going through and deleting all these old posts one by one). In theory I'm not opposed to the idea, we would just need to work out how to make sure it was used only for it's intended purpose.
I've gotten in the habit of quoting posts that have key information or information I think might later be edited or removed. That way it stays true in my post as a quote.
Look at the post below your original one and above my first one, by Tessa Holmes. (Hence my reply.) With regards to your problem, as posts are numbered you can just summarise everything relevant in the original post and state "ignore posts #3, 5 and 6", for example. Not an ideal solution, but a simple workaround.
