Re: Why 2 blogs act like “catch-all”?
Just reporting:
I deleted the “other blog” and recreated it: no more problems.
Regarding the blog ID 1 issue, new users are *not* added to “dashboard” blog (as subscriber) at all, they still go all straight to blog ID 1. The dashboard function is totally ignored other than for its manual import when activating it for the first time.
Waiting for the next patch then.
