I’m using a membership plugin that have different roles and levels. Upon installing bbPress, would it overwrite my existing user levels and roles or append to it?

It will append itself to existing WordPress core roles and capabilities, and adds a custom role for global forums in multi site installations.

[Angela]

so all the existing users will be able to access the forum regardless of their roles?

[John James Jacoby]

Correct.
