Ultimate Branding to change BuddyPress text?

Hiya!

I' was hoping I could use Ultimate Branding to change all instances of "GROUPS" on my website to "WORKSHOPS" instead. It works in some places, but not all. For example, on Profiles, the "Groups" tab is still unchanged. Also, when I view the directory, the tabs say "All Workshops" and "My Workshops," but the search says "Search Groups," and it also says "Viewing X of Y Groups" above the list.

So is it not changing the text in these places because it comes from a plugin (BuddyPress)? I know Ultimate Branding is really meant for replacing Wordpress branding only -- and isn't really meant for all general text replacement issues.

So does anyone have another suggestion on how I can replace the text I need changed?
Any help would be greatly appreciated.
Thanks!!
