This is probably a feature request, but I thought I'd give it a shot here.
Batch Create (along with New Blog Templates) is working great for me to set up student blogs in large numbers.
One of the parts of my process is that, when creating each student site, I use an import to add that student's teacher as an admin on that site. Works great. Now that it's my second time doing this process, I find that I have a need to remove last year's teacher from the site.
It would be great if the batch process could remove a specified user from the specified blog, maybe by including "remove" in the Role column in the import file, or something like that.
Just a thought...
