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.
I run the latest version of Mojotportal and on teh front page i have the blog function.
We are 3 users on the site. Does it work so if I login that visitors se who have typed a post to the blog?
Hope you get what i mean.
As of right now, the blog feature is only designed to show a single author (indicated in the feature settings); it's in the roadmap to add support for multiple authors.
