How to add variables to notices?

[dreamhost]

What files do I need to modify in order to add variables that I can use to the notices manager?

Specifically I am trying to add '$myfeeds', '$myfeeds2', etc...
These are variables created by another plugin for vbulletin that allow me to pull in rss feeds from other websites.

So far I seem to be able to use those variables everywhere in my vb site with the exception of notices which is really starting to drive me nuts....

My idea is simple:
I am trying to pull in rss feeds from specific categories of my wordpress site that directly apply to an individual forum. I have no problem getting the feeds, I just can't get them to display inside the notices box.

PHP variables are not parsed inside of notices. What you can do, however, is extend the replacements available for notices by adding a plugin (look at where notices are processed in global.php).
