How Add Users? Where Documented?

[sakura9x]

How do I add users? Manually (my preference?), by invite (how do I do this). Where is this documented. Also, why could I not find documentation on this when searching for it?

You can manually add members in Admin -> Registration -> Register New Member.

There is no invite system in the core of smf. You'd have to install a mod, if that's what you want.

Are you actually using smf 1.1.x?   If so, then upgrade to 2.0.15 ASAP.

It is documented, depending on whether you are using 1.1 or 2.0, here: https://wiki.simplemachines.org/smf/SMF1.1:Registration; https://wiki.simplemachines.org/smf/SMF2.0:Registration.
