Send a feed note to a group of users (Account Team)?

Hi All,

I know in the feed you can create private messages to individuals using the '*' sign but can we create feed messages to entire Account teams in private as well? Or do we just tell them to use the Feed within the Account object itself - in which case, will all the account team members get the feed message or do they still have to explicitly Follow the account (even if they're part of the Account team)?

Thanks in advance.
