I'm totally open to suggestions as to my next step, but I'm curious what the new entry in ACP/User and Forum Basic Settings would be, given a successful install? Just so I can more easily know what to look for.
Allright, here's what I would do at this point. Copy the "contrib" folder with the installation instruction template under the "mods" folder such as:
I would then access EM through the ACP and launch the installation routine once more. I know at this point that I'm going to get an error on the database update part, because it's already been done. I'm just going to ignore it and proceed with the installation until completion. Once done, User Shield should be installed properly. Next I would confirm that I do have a new entry for User Shield in the ACP:
ACP --> "General Admin" --> "Configuration" --> "User and Forum Basic Settings".
... and this is what you should look for:
By default, it's ON and you should be good to go. Check the "Index" page, specifically in the "Who's Online" table, and you should see a link to the "non-active" filtered list above the line
"The newest activated registered... ". Or, you could also access the "Memberlist" directly and open the sort list, which should offer you a "non-active" filter. Try it out! Don't forget though, you have to be logged in as an admin. to see this. As a user or moderator, you won't see anything.
I'll be waiting for the good news editingfx ...
