Generally, I'm trying to build website that is more like a database of users (of lecturers) that after registation process everyone could upload their own picture and details about their lecture/show/workshop their article/profile.
In the file attached there is a picture of my website using some extension called "TZ PORTFOLIO". This extension helps me sorting my articles in an advanced and graphical design. But the problen is that this extension uses my article list and it does not allow me to restrict users to upload only one article.
This is a link to my experimental website:
Therefore my question is whether I have a way (like a PHP code) to limit new registered users to uploading only 1 article.
(I'm using Joomla 3.1.1)
Thank you very much for your time,
