Either the forum moderator (Donnie) or the Webmaster will need to change that. You can go in and change it with the "edit" feature but it won't affect the actual name of the thread, just the first post. So when you are looking at the list of all the threads in the forum, it will still be wrong. Strange but true.
The moderator or webmaster will need to go into the "admin options" and select "edit thread" to change the name of the thread. I'm sure either one will be happy to change it.
I noticed the typo too, had to laugh. A typo in a quality concern thread, ha ha.
I'd do it myself, but I can only do that in my forum (The ML/GWagen/UNIMOG forum).
