Hm, off-hand, I believe the order of pinned topics is determined by the last activity date. So theoretically, you could use the "Mark Unread" button to arbitrarily bump topics to the top to achieve the order you'd like.
A user in our forum reported the below feedback to me, and I agreed that this is really ugly and hurt user experience:
I just viewed a topic without being logged in and I saw a post I deleted still showing up, with the body "This post is deleted!". I think that's rather ugly and that deleted posts should only be visible to the author and admins.
I'm a huge fan of two-factor authentication, and it's one of those ideas that's been banging 'round my head for the past little while. It's a neat idea and works well in practice because people have always got their phones on them.
SMS 2-factor auth still has one annoying barrier, and that is relying on cell phone networks to deliver the token. I hate that.
I much prefer HOTP (or even better, TOTP), where all I have to do is register the secret once on my phone, and I can use it to derive the token anywhere, even in places where I don't have signal (which annoyingly, happens a lot).
