Hi David - thanks for this plugin which works well for me... unlike WP Multi Network (which I understand is a fork of your plugin) at least the "Create a Network" form in your plugin actually submits successfully in WP 3.4.2 :-)
One thing, however - when I'm coding, I invariably have
WP_DEBUG set to
true and the plugin throws a large number of warnings, which makes WP's admin pages inoperable.
So, I hoped you had a repo at GitHub where I could contribute pull requests, but can't seem to find one. There is a crowdfavorite mirror which is not up to date, but I see little point contributing to that.
If you're SVN-based, I'd be happy to contribute patch files if that would help keep this great bit of work alive and current.
What's your workflow and would you welcome contributions?
