SP Seeing as it's you...
You just simply select one of the four available fonts (which are typefaces really
), type your text and then change the font name in the FONT= tag to the font of your choice. Same as you did with the SIZE= tag.
You can use WORD or EXCEL to preview your fonts, but note that they might not all work.
NAC Not so much really an issue of the software behind the board. The case I saw had a forum called TESTING or something where you could post test messages. I wonder if anyone else read them.
btw, I also tried [br] <br> [p] and <p> which as you can see have no effect.

I'm working at it though
