Basically all I wanted to do was remove the Subscribe/Unsubscribe link from my home page, and not offer the newsletter subscription as part of the account setup.

Here's what I've done:
- Disable newsletter signup at account registration (Admin > Configuration > Show Newsletter Checkbox)

- Removed the subscribe/unsubscribe link from the home page (Admin > E-Mail options > Display Newsletter Unsubscribe Link)

- Created an EZ-Page to link to a page explaining my newsletters and providing the link to subscribe/unsubscribe
