what would be the best way to set up xenforo so that when users join they can subscribe to specific user groups so thier new post are not cluttered with topics they are not interested in. for example if I have a local forum for a region that contains several small towns that are very close and overlap in interest. and I want to keep track of the post about konawa and Asher but not maud. Is it ok to use subdomains like asher.forum.com and konawa.forum.com with a single install? in the root domain. most of the areas have too few to support a lively forum but some may not be of concern to others while some may want to see several of the little areas around them and of course the main cat would host the entire area. I have a vb install were I am getting complaints about clutter from one town that people don't care to read or see in the new post. I am just learning xenforos ways and still need to do some set up and find the right add ons. but this seems to be a major issue and my host suggested that I use something like forum.example.com . at the moment I put the install in a sub directory example.com/748zip but I am not prepared to finish the home page just yet and want to lead folks in to the right place with the simple URL. If I rename that install folder what is involved in creating an index.php in the root to direct it to the right spot. hope this all makes sense if your from a little town you might understand. also is it possible to integrate joomla from a separate domain and host with wikis that are specific to each town? I'm sure confused now cause I am.
