Link Tags

Okay, I lost my formatting bar when I downloaded Firefox, but I want to know how to hand insert the tags to link to somewhere, and choose the text that it displays for the link. Just like in Walt's signiture for Pointbuzz: The Ultimate Guide to Cedar Point or whatever it says.

Here are the examples, just eliminate the space.

[ url="http://www.pointbuzz.com"]link[ /url ]

[ b ]bold[ /b ]

[ i ]italics[ /i ]

[ u ]underline [ /u ]

Thanks Walt
