Small problems posting messages?

[OriginalGriff]

When typing a message, I can add bolded text and italicised text but in CP V1.0 you could also superscript text by adding ^text which was really useful for footnotes. Any chance we could have something added to let superscript work again?

Oh, and by the way, ">" seem to mess your parser up: if I enter double star text with a closing ">" in the text it fails to turn off bold:
Like this
star star Bold>star star Non bold star star Bold star star
Bold>Non boldBoldhello

And - given this is a software site - how to I enter a star in text: x = yz2 doesn't look right! when I wanted ```
x = yz2

And that shows another problem:
pressing "code" inserts markup treble quote,
but shows them as text, 
then leaves everything as a code block from then on ...

Oops!

Gawd I hate markup ... more trouble than it's damn well worth most of the time.
