If you're looking for a way to get rid of fields that you don't intend to be shown at the "Tags" box at the home page:
1) edit the file /templates/base/scripts/BxBaseIndex.php:
- line 862: drop the items you don't want to be shown at the expression " foreach( array( 'profile', 'blog', 'event', 'photo', 'video', 'music', 'ad' ) as $myMode )"
- line 856: if you don't want "proflie" to be shown, swap it for other field at "$mode = 'profile';"
I hope it helps...
Is that true for you?
On a related note: I also find that the photo tab is always empty and never displays any photo tags.
