TOD's are squad bases Mushroom. There are two ways that you can join.
Join a squad that is active in the TOD -- you can get that info here.
http://events.hitechcreations.com/ Click on "weekly events" and the Friday TOD to see active squads.
Or there are usually "guest spots" that squads will have if one of their members can't make the TOD. They will post here or in the General Discussion forum if they have room.
