I have several questions about the messaging module that I will leave below in a numbered list. I would find it really helpful if anyone who is answering could put the number beside the question they are answering so it is more clear for me. Thanks in advance.

1) Is it possible to use the messaging module to send messages to specific user groups? I know the newsletters module has this but I can't figure out if the messaging module does as well. If so, how do I implement this feature?

2) Suppose I am creating a website for different companies to use, call them Company 1 and Company 2. Could I have 2 different messaging modules on the same page where each module will receive different kinds of messages? i.e. one module receives daily and system messages which are directed to users from both company 1 and company 2 where as the second module for Company 1 receives messages just for Company 1 and the same thing for Company 2.

3) If the messaging module does not support these kinds of activities, is there any other module that does? If possible, include a module other than the newsletters one because I want the messages displayed on the site, not sent to the user emails.
