Got a response on the BuddyPress forums, and it did the trick. Long version below, but the short version: change the "archive slug" and "single slug" names in the "Forums" settings, then create a custom menu. Create a custom link to the new name you specified in the "archive slug" section of the settings, and voila - all set!
LiIttle something i learned as a newb.
Activate your forum next thing you’ll want to do is then go to your settings you’ll see forums on the bottom
You’ll see archive slug and Single Slugs rename in the forum base and then in the forum slug below aswell. Because forum actually conflicts with the sitewide forum. let’s say name your sitewide forum bulletin board or support. The group forum natively is the forum on the header menu. Which you can later rename..
Now you want to make a topic go to topic in the forums. Click you’ll see “all forums” and “new forum”
I would click new forums, here you name a topic of interest. let’s say general discussion name your topic and below give a basic Description(optional).
Now you want to save it you’ll then see a link look at the link copy it. but only copy
Next thing you’ll need to do which is the final step. Go to the appearance section. You’ll see menu which is you site navigation menu. You’ll have a few things you have to do here.
First make sure you make a custom menu or which now the main theme allows you to or you can make a custom menu name.
look at the section on the top left corner a drop-down you click whichever theme is named or you select as your menu save .
Now go down to custom links remember that link you copied earlier(http://www.example.com/support) paste it in there and name it click add to menu.
Now you have a list you can now rearrange move or even create a drop-down menu on. What i did have activity /members /group and with forums i renamed that “group forum directory” moved that slightly to the right which creates a Drop-down, then the site wide forum which i named support or whatever you want to call it. Now save. DONE!!
Go to your site homepage and everything should be there. Best of luck!!
