Groups not showing from profile pages (only from dropdown)
Using Jamroom
Holly, I hear you, but:
the way it's set up, a regular member will see a TAB (say for Photos/Images) on their own profile page even if they have not added any photos yet- but they'll see a big PLUS(+) button there when they click on the Tab. If you have DISABLED that quota from being able to create groups on their own (as I have in my site as well), then the only difference is the Plus button will not show to them. The idea of having the tab there even if they don't have any photos is to encourage members to add some when they see the Plus button in the blank tab area.
But YES, I see your point in not wanting the profile page TAB for Groups (or Images, Audio, etc) to SHOW for a member at all IF you have disabled their quota from even being able to create/add that type of item. That it frustrates and confuses the member. So to clarify... THAT is what you are asking to be able to somehow achieve- to HIDE the TAB if that quota is not allowed to add or create that type of item anyway.
One possible complication I immediately think of concerning this though- the ning members you import over...some of them will perhaps already have items they added while on your Ning site...that your new site now prohibits them from creating or adding for the future. If you HIDE the Tab from them, they then will not be able to see/access their own items anymore then... this could cause issues if your proposal was implemented globally. So this might be a custom code thing just for your site, to avoid such issues from effecting others' sites.
