Two new observations.
No post URL. Bummer. Looks like you can only link to the thread, not a specific post.
Yeah, that is a bummer. Not sure if that was an addon feature or not, but it shouldn't be that hard to implement, since the board does generate links to specific posts. It just doesn't put them on the page for you to copy.
Also, I keep getting logged off as I move around.
If I am not logged in and just put my user name in the box when I reply to a post, it tells me that name is taken.
I think your getting logged out because the session cookies were set to expire after one hour. I increased it to 2 hours. Not sure what's a good value for that. But, if you check the "Log me in automatically" box when you log in, you'll stay logged in for one day, with the current settings, assuming that's working right.
And the posting/login thing works a little different. You can actually use a username in a post without registering or being logged in, but only if that name isn't already taken. So, if you're a registered user, you have to log in using the link up top, before posting. I guess that could be a pain in the ass if you forget to log in, but that's the way they did it, for whatever reason.
