Piratepad is being very fussy at the moment - for the moment we should rely on forum posts, elementscommunity chat (although be very careful, a slip-up here could be costly and would look very, very bad) and the chat in our
Vault, although that last one only works when other people are online, and doesn't save chat history.
In general, posts > gdoc chat > elementscommunity chat.
Piratepad's fine now, and has been for a while.
