Have you tried the
vB code? For most uses it will do what you'd otherwise want HTML for - note that the link above does the same thing as an HTML <A HREF=...>...</A> link, but it was made using
vB code. I was looking for HTML support at first as well, but have found
vB to fit my needs here. FWIW, HTML is often turned off for boards like this because it is a potential security risk for executing malicious code.
