drmike, again thanks.
Sorry I was talking about plugins that don't work in the mu-plugins directory so have to be put in the plugins directory.
I am poking around the code, but since I am not much of a php programmer I have a hard time scanning for what I want. (By the way the PHP for Dummies you recommended is getting ordered this week. That should help.)
I wasn't sure which files were used with the creation of a new blog. upgrade-schema.php, and wpmu-functions.php had both come up in the formum, but I wasn't sure which if either would be involved in setting up non mu plugins. Again sorry for being vague, sometimes I'm not sure how to best explain things.
Since I am not letting the users (students) create their own blogs, is it possible to change the default user from admin to something else? Or alternatively if I edited the administrator role in upgrade-schema.php would this be an alternative? Would editing the administrator limit the rights that the site-admin would have in that blog?
I appreciate all your hard work helping me and others in these forums. Can I get you a small something (sorry limited funds) as a thank you?
