Larger Broadcast Message and Attachments to vmail

I am experimenting with VarAC and like the program. Our group often broadcast messages one to many. I would like to know if you can increase the broadcast message size from 150 to 500 bytes. That should accommodate our needs.

I am also interested in the ability to attach files and images to vmail. It would help us to have that capacity. Please let me know if this is possible.

Thank you,
