To help people provide UBB and HTML help to others without using stand-ins like "{" for characters like "[" (used by UBB codes) and "<" (used by HTML), here are the literals for some common UBB and HTML characters:
<   <
>   >
[   [
]   ]
&   &
So if you had typed this into the message box:
e=mc<sup>2</sup>
It would have been displayed like this:
e=mc2

This isn't really true, is it, that we have solar evidence that tells us the sun is 4.5 billion years old? Isn't the solar evidence more approximate? I guess I always assumed the 4.5 billion year age was simply implied from the age of the solar system derived through the traditional dating methods of both terrestrial and extra-terrestrial material.

Thanks for the details - I didn't realize such calculations were possible.
