UserList with MosTree?

Hello,

has anyone set up CB and MosTree together?

What I mean is I would like my CB users listed in a MosTree category.

I assume the best way to do this is with a CB Plugin, similar to the geocoder plugin. Alternatively, this could be done on registration and I could manually import my existing users.

the other option is to run a cron job, however I would rather this be done automaticly.

and help would be appreciated.

anyone even have advice on how I could tackle this? I am a developer... just need a little help here.
