Our board accepts both HTML and BBcode. If you're already using HTML tags, there's no need to undergo the effort to switch them over to the BBcode brackets.
From our
New Tea Room Orientation post:
Do we still use html tags when posting?
Yes. When posting to the new board, you should still be able to utilize the html tags we all know and love. And...there is a check spelling option; it is set on American English. We can still use smileys, and images are easy to insert. The buttons above the message text add tags for you in BBcode, and, of course, those work in posts.
Note: I used both HTML tags and BBcode brackets to insert the above quote, just to demonstrate both can be used simultaneously too.
