Firstly, my oldest friends on PC who are still presently holding the status, are Vendak and Patchisou Yutorhu. Two members to whom this day I speak to quite frequently in comparison to most, even though it is in fact seldom, compared to the rate at which I speak to Hiiro and Morkula. However in saying this, the latter names would be members that I've actually respected and been close to more than anyone online. A notable mention would be Manipulation, all of the latter members with the exception of Morkula, have been around for almost my entire PC history and have each moved up in the world of the forum, either into a staff position/promotion, or more importantly; into great posters and fantastic characters. I can safely say that each member has had an influence on the "Abnegation" you see today. I would say that it's been 100% positive influence also, in one way or another.
I suppose, that I've fallen into a slight group of friends upon my interest in Game Development also, in which I do speak to on a daily basis. Some of those would be mecurysky, Dr.Octagonopus, Cilerba, hourglasshero, ben., The Dewitty and more. But those guys would be the ones I speak to the most.
I also met a lot of people through the irc, some of those would be Jakeyboy and Logiedan who I've probably hit it off with the most on there, I also speak a lot with Amachi and countless other members in PC's javachat.
I've also been friends with Forever, Signomi, Aizuke, Franceschi, Blazichu and more from group convo's on MSN. So over the year, I've met a lot of people. Over 150 friends I suppose and well, a lot of great, great people.
