Plugin is great. Can I delete it after it the site is set up to multisite.
Thanks. Yes you may.
When I install ‘enable multi site’ it installs OK but then I lose
all my options in the ‘Plugins’ menu. Cannot add new plugins
or uninstall the ‘enable multi site plugin’ I have used multi sites
on this domain for over a year until my site was hacked into last
week and I lost all my multisites. I have had my hosting company reset my account twice already and it looks as if I will have to ask them again and then forget about multisites, unless you know of any other way to get my ‘Plugins’ menu back.
Thank you
Marian

I have been struggling around to make this Multisite enabled. I was looking at a lot of extensions and explaination. Now its great. Everything is described in here with summary. Thanks
Is this plugin still working for WordPress 3.5? And do you have any experience of creating Sites in a Network which is placed in URL path under another Network?
any ideas when v2 will drop?
