Unfortunately, allowing HTML is either an "off" or an "on" proposition. You can't enable a subset. And the decision was made to turn it off. I think it was the right decision and I will stick with Paul on it.

If you wish for PNG graphics, font tags, and table tags to work in this BBS software, there's little that Paul can do about it. Perhaps post on the Infopop forums and ask the developers of the BBS software about these things.
