As I understand it you are only not allowed to advertise other shards.
Now does that mean offline games are still ok (If so get that to staff please)
Second can I start a thread on games to avoid? I have a junk e-mail pile of games invites that for example say free to play then you get there and find that it's free if you buy another game or sign up for a set. Just an example.
Sorry but every time I read the codex the same two staff tell me I'm wrong about everything and really it's just too frustrating.
