Such an option would be problematic in threads where much quoting has taken place. The current setting gives you 15 minutes for going back and editing a post. This may even be too much for fast moving threads where lots of quotes are being made. It is something we are keeping an eye on.The new layout is fantastic. Sorry to be a pedant, but how does one edit posts that you made a few hours ago? I see that it now lets you edit posts that you have just written, but not ones that you wrote a few hours previously.
