Copyrighttext in footer question

[Boofo]

I have this code:

$copyrightyear = vbdate('Y', TIMENOW, false, false);

Now, is there a plugin I can use for that that will work in the "Copyright Text" option in the vbulletin options?

I want to have "Copyright ? $copyrightyear MySite.com" in that option but would like to have it automatically take care of it each year. I tried adding it to there, but it doesn't seem to want to parse. I have tried the global hooks and just about any other hook that I could think of to make it work. Any ideas?
