Thank you for pointing that out to me.
So, I opened an up.html file in each blog, pasting in it the code you wrote, first, for the main blog, then for the secondary blog. Then I pasted relevant parts from the last source example displayed in the tutorial in the Main Index templates of the two blogs.
When checking main test
blog, there are two blogs, but data is identical and comes from the main blog. When checking the URL for the secondary blog, it displays one blog, which I guess is as it should be, since the secondary blog is not meant to be visited alone.
Please, what should I do here, doctor, in order for the secondary blog part of my main site to really display the content coming from my secondary blog ?
An aside question: I see you can write in different categories. Say, you only want to make up two categories and display them in two separate columns simulteously on your weblog page. So that when you write a new entry and select to put it in category 'a', it goes in the left column, and when you select category 'b', it goes right to the right one. It seems simpler than two blogs, but is it feasible ?
