I missed or don't remember that post.  My vote is replace "Back" with "Delete" - or "Abort"

Just read what I wrote at elog:67983

Just to comment that the expected emails that one would have expected with the last two entries have either
been held up or simply have not been generated and sent - both the preceeding entries were submitted by using the "Back" button, this time I'll use the "Submit" button, which should generate a email.

Just to comment that I submitted the entry below by pressing the "Back" button!

Hi Stefan,

I had started to write a completely different bug report, but then realised I had not checked a detail.  I had written about one sentence.  So I decided to abort the message, and hit the "back" button.  Only I found that this had created a new entry in the elog listings.  I immediately went in and deleted it, but I had expected the "Back" button to have aborted the entry (as it does in 2.9.x) not to submit the entry!

It doesn't seem to have created an email, though.  And for the sake of all your users, I'd not want to experiment here on the matter too much!

> Another strange thing: the draft got submitted when I hit the "Back" button after reopening it.

Well, this is a problem indeed. When edit entries now, drafts gets saved regularly, overwriting your original entry. This is a limitation of the elog database, which cannot do full versioning. So "Back" is actually the same as "Commit without email notification". Or better "Commit some ten seconds ago". Now I 
don't know what the best solution is. I'm tempted to just remove the "Back" button and replace it with a "Delete" button. So people can either submit an entry or delete it completely. Any thoughts?

Yes, I saw it on bitbucket, also all the commits. Thanks!

Also this made it now to the docs. Thanks.
