What does 'closed" mean?

[NC_Coastal]

Closed. Closed for. Closed to.
Can someone explain these terms?
Thanks, I'll hang up and listen.

It just means they don't want anyone except the person(s) they're writing with posting in the thread.

Whereas if it said "open," then anyone is free to write in the thread - although, of course, you're expected to play along with the setting and story in the thread.

Well put, thank you Scuttle!
