[Plugin: Secure Invites for WordPress MU] More info please

I think dealing with forums for so long has spoiled me. I’m used to installing mods manually but they usually say take this code & shove it on this page in between these lines. Or replace this code with this code.

Are you saying it’s already defaulted to say either your message went through or it didn’t? So then all I really need is your one code free of yay & oops. I’m using the Arras theme at http://dawnswebdesigns.com/family-site…can you please tell me to shove what code on what page in between where?

Also I can’t see 2 of your screen shots (top & bottom). Only the middle one’s showing up on my site. I got one link (invites) under site admin & it links to invitation list, settings presets & special users. After I put this code some place will links to the other 2 screen shots appear or am I already messed up & don’t even know it? Thanks for any help.
