If you are having people enter passwords, you should really have an SSL certificate.
It would be nice to be able to select a username instead of just using a number. It is far easier to remember "nickname" instead of ####. When I am looking for a message, it would be easier to search for a nickname, rather than trying to remember some random-ish number.

The ABC BoD has approved the funding for the SSL cert, but I just haven't had time to make the purchase and install it. It's high on my list though.
I use the sig in the forum to let people know who I am and how to contact me.
