3: When using Quick reply I find that system seems to stall does not seem to post the reply and return topic being replied to.
I'm not sure if this is what you're seeing, but it is closely related, so I'll post it here in case anyone needs it:
There is a profile option that you can set to change the way the board reacts to replies. By default, the software assumes that you're finished with the topic after you've replied, so it takes you back to the topic list without ever showing you the reply in the topic thread. If you're not used to that, it looks exactly as if your reply has vanished into the ether!
If you prefer to see your reply in place, so that you can check it's there and/or do a final proofread, you can get the board to show it to you.
To do that, go to the "Profile" menu near the top of the page and select "Forum Profile", then go to the "Modify Profile" menu a little further down. Select "Look and Layout", then check the box marked "Return to topics after posting by default." Finally, click "Change profile" to save the update.
