If you have questions about using mojoPortal, you can post them here.
You may want to first review our site administration documentation to see if your question is answered there.
Is there a way that you can set all registered users as trusted users? I'd like people who register to be able to add images to their posts.
I just created the article Allowing Users To Post Images in the Forums, and I verified it works on the demo site as described in the article. I do not recommend marking any user as trusted unless you know and trust them.
Hope that helps,
