I am curious, exactly what changes do your users have to make? And I am equally curious as to why YOU had to change the files? I did provide you with all files and vB file edits 100% (if we disregard the if() problem above) working, so if you are indeed saying that you manually changed all files from YesNo to 1/0, then...meh I will keep my comments to myself

It's not like you have provided patch instructions for file upgrades for a long time, you always just say "reupload $files".
Of course, you CAN use Yes/No with the $vboptions as they are setup now, but it's more "vBish" to use 1/0

Yes/No, 1/0, whatever. It is of no difference
