I have fears with the invite friends function if this network scales up. I already had the first SPAM bot on my network which got through the reChapta and registered a user automatically and repeatedly. The SPAM bot user is blocked manually and the domain that was used to register the users is blocked as well. I feel that it is only a matter of time until those SPAM bots learn how to send SPAM e-mails with the invite friends function from the admin@nerdsnet.net e-mail adress through my network. I would prefer to have the invite friend function send an e-mail with the FROM - adress of the registered e-mail adress of the user so that I can check in the SMTP tool (e-mail header) which user SPAMs the world through my network. (Feature Request)
