Any chance we could get superscript and subscript tags? Considering that Wint keeps asking math-related questions (and I end up answering them) - and superscript tags would also be useful for those cases where people want to make footnote-type references to other posts - it'd beat the hell out of the current "you can half-*** subscript with [sm][/sm] tags, and NO SUPERSCRIPT FOR YOU".
It's not like they can be abused in the fashion of [lg][/lg] tags, other than making posts that use small, double-spaced text (which wouldn't be harder to read anyway...)
