I trust this site 100% even though I have only downloaded the RGR plugin. If you still feel it is best not to download the plugin, remember that you can still play some games with just an updated version of Java.
I understand if you and/or your father cannot trust this site. Too many hackers have tarnished the online experience for people everywhere.
NovemberJoy : Here you go! As I said just type in the username of the person you want to summon, and put a colon ":" beside the name. I am sure you have gotten two notifications because of this. The local moderators are lecacyme3 and Bnuge. Go ahead and try summoning one of them. Be sure to tell them that you want this closed.
