@KTS915 - nice to see you here too :)

@Alec - Need your private email address, tried finding it on the site after I signed up, but couldn't. Would love to become part of this!

Naming indeed is quite difficult and I (obviously) noticed that you have the domain for BusinessPress already. Wouldn't do that for several reasons, mostly the fact that people will most likely mix it up with both BuddyPress and maybe even bbPress.

Although I understand that you want to stay close to the software you fork from, you can also add something about WordPress in the byline.
For example:
[name] the business version of WordPress.

or even without WordPress (they might sue you):

[name] the better CMS for your business.

Take the fork of Jigoshop, that became WooCommerce

We will come up with something, no need to rush that yet...
