With v4, if you were creating a post then accidentally navigated away from the page (as we all do at times....) if you hit the 'back' button on your browser you'd get the recreated part-post as you left it. As we have all found to our cost, with v5 if you leave the page while composing, or computer crashes etc., it's gone: 'back' just takes you to a fresh 'reply' pane.
This solution ain't been advertised widely and I found it by accident:
Go into your 'profile'. Find 'edit profile' then open 'settings', 4th from left on blue(-texted) bar.
Top section is 'forum preferences'. 4th down is 'save drafts'. Change to 'yes', don't forget to 'save changes', exit and you're done.
Now, every time you leave a partially composed message, it acts like Hotmail/Outlook, and whatever happens in terms of page closing, browser crashing, negligence etc., the first thing you get when you come back is a popup box telling you you have a draft and if so do you want to restore it? A 'yes' here puts you back onto the original compose screen in the correct place on the correct board.
Far better than v4. For once a genuine thanks to proboards for a real improvement - - once you know about it!
BTW, this thread will be migrated to the 'how to do' board once everyone's had a chance to read it, but it's far too important to start it off hidden well away.
I logged on just now and the software suggested my username for me, with a space in it (as it grammatically should have). But of course spaces aren't allowed in usernames, so why are they allowed in suggestions?
