The site usage is free for any member but if you need more functionalities for professional usage you can start a paid membership for the announced functions on the explanation about different membership types.
In some cases, the administrator or moderators assign a special membership type to specifically elected members. This special membership type is not visible in your profile : it will display "Free membership" but the functions have been overruled.
Rome is not built in 1 day, so does our site. We are continuously evolving and we listen to the suggestions of our members. We have a quick list of mid term plans listed on page of planned expansions which are based on user input, so far. If you want to express your priority or if you have your own suggestion that is not listed yet, feel free to tell us via firstname.lastname@example.org.
The hints in our article "How to upload photos" will help you.
