I feel any member should be allowed to create a group and forum for that group. So although there have been some recent mishaps please feel free to create as you see fit. Afterall this site was created for its users.
Just keep in mind that when setting up a group : if you did in fact want a message board you will have to go into Group Settings in the Admin link of your Group Home Page and check the box to enable a Discussion Forum.
If you need help just shoot me a PM.
