Most common bbtags are supported, and with cbparser's InfiniTags™ you can pretty much just make up
tags as you go along. If cbparser can construct valid html tags out of them, it will. Experimentation is the key, and preview often.
A few
bbcode examples..
[b]
bold[/b], [i]
italic[/i], [big]
big[/big], [sm]
small[/sm],
[img]http://foo.com/image.png[/img], [code]
code[/code],[code]
teletype[/code],
[url="http://foo.com" title="foo!"]
foo U![/url],
and more..
To post code with indentation and/or strange characters, .htaccess, etc., use [pre][/pre] tags.
