Here's a bit of a random one that just occurred to me and it's no big deal, I'm just curious...although while I'm typing this, I think I may have just worked out the answer to my own question!
I was wondering if when you set up  a forum, you can mark certain certain words and by which I obviously mean real names, so that they don't constantly come up as spelling errors?
But it did just dawn on me I should be able to add them to my own dictionary, shouldn't I?
