In the WAM Games group, many of the threads have been created with a gender, that means that some users cannot see all of the threads. We use such settings to essentially filter out what we class as spam, the things we aren't interested in seeing. But in the Games group, the threads should ideally be viewable to everyone. Not sure if there's a way to set threads there to default to general or not, if people can't see something, they can't join in in!
I can set a group to not have a gender option, which means all threads would be seen by everybody. Like the Off-topic forum and this group. I'm not sure the whole Games group would want it that way? Individual threads can still be set to n/a on gender....
