I have set up two forums on Google Groups to discuss this project. They are configured so they can be used as a mailing list or a web forum. To post you will need to be a group member. If you have a google account you can add yourself as a member. I will need to approve it. If you don't have an account and don't want one I can add you as a mailing list member. Email me at the link at the bottom. In this case you will not be able to post through the web interface.
The first is MFM Announcements This group is for announcements about the project. It will be a low traffic group where I announce things like new versions of the software. I recommend subscribing to this to get email of each posting.
The second is MFM Discussion This group is for general discussion and support. It probably will also be a low volume group.
