Nope sorry, i was using the wrong variable :-p i applied the correct one to my post RIGHT as you were posting that :-p so recopy whats up there ^^ and it will work :-p
Alternatively, you could use $vboptions[homeurl] instead of the bburl, but keep the trailing slash (the option requires you to ignore it, but i would rather copyscape was happy with the completeness of the url). heck, you could put whatever url you want in there (hardcoded). you could even dynamic it up to search that EXACT page your staring at :-p
Also, i noticed that copyscape more like searches for large matching swaths...so practically every vbulletin matches my vbulletin because its using the basic style. great to see whos stolen your styles or uses your hacks OR WHATEVER
