What I understand is, you mean an edit history visible to public. At the moment I guess only mod/admin can see edit history, not sure though. Publicly it's not available however I think it should be publicly available too.
I don't think so. I know Mods can't see edit history, and about Admins seeing edit history, I don't know if they can/do see for every single user, but theymos said he tracks the edit history for least trusted users like say, TradeFortress.
As far as I know, Facebook used to show this message "last time edited 00.00" (I don`t use FB) or something like that, showing the readers that the post was edited and the time of the last edition.
Now it just shows as the comment has been edited. I don't think you can edit messages(Personal Messages?DMs).
OP, if you want to keep track of your edits, you can keep track of it in
Drafts, but it only lasts for 7 days.
Is this on btct forum? Let me try this when i got a hold to a computer. How about for mobile users like me? Any suggestions?
You can see if someone edited their posts while on PC, there's a dotted line below the date area of the post. You can't check if the post is edited or not via a Mobile browser.
