I am using  version 13 Pro and would like to be able to offer a forum section within my website. I would like it to have several sections each of which could be run by someone other than myself. Each forum would be a sort of question and answer or discussion on a specific subject. I cannot really see that working with the X5 blog utility and I would imagine I would need some separate software that could be intergated into X5

Background I am running a U3A (University of the Third Age) website and we have several interest groups and they would like to have a space dedicated to their interest group. They would manage it and post stuff for the people that have indicated they want to joing the group. 

It would be something they could access via the U3A website but would require then to log in so that only members of that group could see the content.

Any thoughts on best wasy to achieve this

Thanks
