Steve, yes I know that you can edit for 72 hours, but I would like to avoid the edit message at the bottom of the post, "Last edited: ...."
For example yesterday I made this post at 9:54 PM (my time),
Post on speaker cabinet resonances
and at the bottom it says: "Last edited: Yesterday at 10:00 PM" (my time, on other screens it will say another time according to their time zone).
That is just 6 minutes after posting. I edited last at that time because I discovered that I needed to clarify a sentence with a comma. If I would have edited within 5 minutes (i.e. had I been one minute faster), no note "Last edited" would have shown up at all at the bottom of the post.
I would like to avoid such notices at the end of the post. On the old WBF forum you had 10 minutes instead of 5 minutes time to edit before there was a message "Last edited" at the bottom of the post. I would like to have that here too, thanks.
