Sending messages to multiple members

Is there any way to send a message to multiple members that are in a group you are an admin in?

For instance, we are playing an internal tournament and I would like to send a reminder message to the members who have not submitted game results yet. I would like to send the message to 8 members at once instead of doing it one member at a time.

Thanks for any assistance.

This is what your notes and news are for. :) This allows the members the prerogative to pay attention to the notes or not. If you send messages to multiple members, and all the messages are exactly the same, your account could be closed for spamming. 

Thanks for the response.

I understand the news and notes section but wanted a way to try and get a direct repsonse. 

Could you explain why would it be considered spam if they belong to the group and have agreed to play in a tournament? It isn't like I would be sending to Chess.com members that are outside of the group, just to ones inside the group.
