I seem to be having a support post each day at present :-o.
I have two blogs http://peterthomas.wordpress.com (business-related) and http://trnovice.wordpress.com (not business-related) - the former is linked to the user ID I am using to post this, the latter to a second user ID.
However, both blogs were originally allocated to the one ID I am posting under here and I had them surgically separated by WordPress after getting some advice on here.
I now use this ID for the business blog and my other ID for the non-business one, which is fine and works great.
However, I have just noticed that categories from my business blog, e.g. "business intelligence" or "cultural change" have started appearing in the lists on my non business blog (alongside "rock climbing"). Now this is not the biggest of deals, I don't have any posts using this categories on my non-business blog, so they don't appear anywhere on the site, but I do have some redundant options clogging up my dashboard. I'm loth to delete them lest they get deleted from my business blog as well (speaking of which I had better go check that rock climbing and mountain biking categories have not appeared on my business blog).
Has anyone else had this problem?
All the best
