well as always in the computer world stuff changes...at this point we need to upgrade the forum software due to it having some security bugs...and I think this might also have had something to do with Tim's forum getting hi-jacked several weeks back as he runs the same forum software.
Anyway here's the fun part...this forum is v1.3 which is no longer supported, we can move up to 2.0 but it's the paid version. Yearly it will be $69.95, or a lifetime license of $199.00.
We have the option of switching to vBulletin (vBulletin.com) for $85 a year or $160 one time/plus a small renewal fee each year for updates...the only catch to this is we have to convert these forums over to it and get used to it all over again. Although I will say vBulletin is the best when it comes to forum software, if you wanted to post from your cellphone vBulletin can be setup to let you do it...the list goes on...
Either way we do this I'm going to end up spending some cash on it, so it's now just a "what do you want" kinda thing...
go have a look at both of them
