I'm a dork, I figured it out.

Post your question and answer in case anyone else runs into it ;)

Pretty simple...if you don't actually install ALL the files into the proper places, it won't work. lol

The Upload folder includes:

.php files: These go in your root directory on the site (where all the other php files are at)
AdminCP folder: these files go in the AdminCP directory on your site
Images folder: these files go in the Images directory on your site

Yeah, I'm a newbie, but now that I've figured it out, I'm installing hacks & mods like crazy. LOL Yes, I'm really Oh So Blonde!!!

How would I go about limiting its use (or its view, for that matter) to a single specific forum only?

Well, you could use conditionals to show the postbit ratings in one specific forum, as well as any navbar links. But the mod itself isn't forum specific. Ratings are given to users and on it's own page.

Could you tell me how to do the former, please? I really only want it "showing" outside of the forum it's meant to be utilized in. Thanks.

Is there a way to prevent specified usergroups having a trader profile?
Have tried for a while with is_member_of but it seems I can only prevent
users of specified usergroups seeing trader profile.

Thanx for any help.

Here's a list of template conditionals that should help you:

Never mind I'm just tired I figured it out.

It tells you which templates to add them to. You then put them wherever you want them to appear.
