Additional categories for Discovery

This app is designed well enough to compete with corporate offerings like SLACK, google Voice and other products.  I would like to see Discovery made available to 'Other' Corporations, Non profits etc who want to use this as an official means of communication for various think tanks, support and misc.

I represent a 501c(3) group that is considering this as an official communication medium; but the three options for listing in Discovery are not applicable to us.
