So far those are teh only tags added/allowed.
Some don't work as they are not the right commands to add to the board config, however D-Day is looking for the phpbb codes to enable the HTML.
*kicks D-Day to remind him*
State which HTML commands you want enabling & I will confirm or deny if I am prepared to add them, this depends on how much of a security threat they could pose too the running of the board/hackability/script kiddies etc.
As most here are trusted I don't mind most HTML being enabled as I myself miss certain things I can do on other boards with them. It also narrows the scope of what stuff people can learn in the testing forum. & as that place is somewhere I want to be used too teach people or let them learn from others testing/trying stuff I wouldn't mind getting it more flexible. :)
