Blog ALL and Aggregating blogs
b2evolution version 0.x & 1.x only – does NOT apply version 2.x and above
Blog #1 automatically aggregates all the content of all other blogs.
In B2evo 2.x & above, any blog can be set to aggregate any number of other blogs by entering a list of individual blog IDs to aggregate.
A common mistake
One of the biggest errors new users make is choosing the "Blog All" as their primary blog page. "Blog All" is a special blog that shows every post that is posted in every single blog on your site. "Blog All" is useful for many things, but it is not intended to be your primary production blog.
The prefered method
If it’s just you, and only you, who will use the blog, using "Blog A" for all your content is a good choice. Recycle "Blog A" (rename it and deprecate all existing posts). If you only want one weblog you can hide "Blog B" for the time being. (Again, we don’t recommend deleting it right away. To hide a blog, open the "BlogSettings" tab, click on the blog you want to change and in the "General" tab under "Default display options" uncheck "Display public blog list" and "Include in public blog list". (This appears to have changed. If you go to Blog Settings >> Features find "List of public blogs" you will find the option "Include in public blog list:" where you can display or hide your blog.) Many people start expanding their sites with multiple blogs after they get used to how b2evo works.) The "Linkblog" you can use or hide, depending on whether or not you want links in the sidebar of your "Blog A".
Just for the record, there are no ill effects if you simply decide to delete everything you see and start from scratch. If that works for you, go right ahead.
But still : don’t use blog 1 (aka Blog All) for actual blogging…
