There are numerous occasions where posts are edited for valid reasons, such as announcements, pricing, links etc. on posts that are revisited very frequently. When they're edited there is no easy way of knowing what the actual edits are apart from knowing when the post was last edited. If posts have changed since the last time you visited a thread or read the post, it would be great if it the edited components were highlighted in some way (different font style, highlight, background colour change etc).
+1. OR atleast it would be great if something like 'Edited on Date,time' is shown if the user edit his/her post. So we can know he/she has edited his/her post.
P.S. Sorry, what I wanted is actually implemented though 'not fully':
Everyone can see it, its not very well displayed but look at the timestamps of messages, if they have a dotted line under them it means the post was edited, hovering over the timestamp will also reveal when it was last edited and by who.
