What variable in the code is the path to the forum and home page?

[StephenKay]

Hey, thanks! - excellent resources.

However, I'm a bit new to this, so as a test I put this into a plug-in that is on the "global_setup_complete" hook:

echo "<font color=#FFFFFF>";
echo "bburl " . $vboptions[bburl] . "</br>";
echo "homeurl " . $vboptions[homeurl] . "</br>";
echo "</font>";

...and all that it prints at the top of my page is:

bburl
homeurl

...so the variables are not there (or perhaps not initialized yet?)

Basically, I want to initialize something one time that will then be used by other plug-ins.
