I see you are an administrator of AviTron. Then you are exactly the right man to answer questions. We carefully studied the AviTron page on Facebook (https://www.facebook.com/groups/299061101879948/), but we only find a lot of photos of dancing avatars and some photos of regions. But no answer to the question why my friend e.g. can neither teleport to my region nor visit almost all other grids. Where is the mistake, is a setting wrong. I can go wherever I want but my friend can't. Why?
