First - Note on the Hub list that the EPAV Hub does not appear:

However - if you look at the Bookmarks list (where I had some time ago bookmarked the EPAV IP address) it does appear - as 'Online Hub':

Secondly - Also note on the Bookmark list above that my Hub - identified as 'My IP' (which is running on a separate computer than the one looking at the Hub list and Bookmark list but is on the same LAN) is on the Bookmark list as 'Online Hub' but is also not appearing on the Hub list.
