Invitations - Safe to use?

Stewartiee

Hello.
I just found some code to allow invitations to be sent out to e-mail addresses by a user. However I am a little concerned if it's safe to use since I don't see a link to it anywhere on the profile. Is this on purpose? Or is it safe to use? It does seem to work...

For others interested, if it hasn't been found before or if I just missed the link for it, you can find it at /profile/invitations
