Hi Urban,
Look below where you are typing (either in an initial post or a reply). There is a section labeled 'Instant UBB Code' where things like bold, italics, etc. can be used.
Or if you prefer, you can just type the UBB code tags in (I had to include spaces after the initial brace to actually show the tags):
[ b] text [ /b] - bold text between tags
[ i] text [ /i] - italic text between tags
[ u] text [ /u] - underline text between tags
You can also combine them:
[ b][ i][ u] text [ /u][ /i][ /b] bold, italic, underlined text between tags
