I've read through your instructions and forum and it is still unclear on whether to network activate on multisite.
I have a multisite (as standard, all sign-ups are from main blog), however, also as standard, new signups are not registered users on the main blog.
I want to send the automessages to all new blog sites. I do not need to provide the subsites with the ability to send their own automessages.
It appears from installation instructions that in order to send to new blog sites you need to network activate. However, there are no settings in the network admin. From which site do I create the automessages? I assume, my only choice is the main blog, but the new signups are not associated with the main blog.
Please clarify the proper method for my use case. Is it network activation or per site activation? And which site to use to send messages to all new blog signups?
