MTOtherBlog allows you to place the context of tags into the context of another blog id.
So you could include a posting listing from blog a on to blog b.
It does NOT rebuild blogs for you, you would need to do this manually. There is a plugin that can make this very simple:
http://www.pyrojection.com/rebuild.htmlThen, what you can do is include in the templates where mtotherblog is getting information, something like this:
CODE
<MTOtherBlog blog_id="1">
<$MTRebuildIndex template="Main Index"$>
<$MTRebuildIndex template="Side Menu Include"$>
</MTOtherBlog>
Basically, that says 'when rebuilding this template, also rebuild the Main Index and Side Menu Include in blog_id 1".
I have found this invaluable.
That siad, if you can, at any time you should use php or otherblog., There are times you can not (context sensitive information, interspersed entries) and times that you can. I use this becaues I have MTGlobalEntries compiling posts from 6 blogs onto my blog id 1, But if you just wnated say, a list of entries from another blog, a php include is much better and won't require this extra rebuilding step.
does that help?
