Nice to see that you've already asked the question I was just asking myself these last few days and that timethief provided the answer(s)!
BTW, thanks timethief!
I'll share another question that perhaps either of you've already thought of it as well:
How about pages with posts in different languages?
When I tried creating my second blog in French, I came across a problem:
I couldn't find the way to edit my contributor's blurb.
If I modified it for the in French blog, it automatically replaced my initial blurb.
I'm sure there's a way to seperate the two.
Has anyone the answer? Thanks a lot.
