FYI – If you have a forum marked as private, the update does NOT appear in the Activity feed. It only works for public forums.
I had exactly the same problem as you did.
I wanted an easy way to update the email that new users receive.
After learning that the emails are not sent through bbPress, and instead through wordpress, it was easy to find a better mail plugin that would do exactly what I wanted. I found WP Better Emails.
It is an HTML (or text) based email plugin that looks much more professional than the usual text based message that WordPress sends out.
Now, my new users receive a nice little message with links to specific forums:
Introduce yourself, Popular Posts, and Forum Rules.
You can see how I use it by visiting my forums and signing up. I’ll delete you after a few days if you let me know.
are mod rewrites enabled?
