My assumption is your intent here is to prevent duplicate/spam accounts. That makes sense. More and more websites require their comment sections to be tied to a facebook account to give the user some skin in the game. I don't think this is some "cash grab" to "force" users to buy the game, as a couple have suggested. It's very unlikely anyone who hasn't played the game by now goes out and buys it solely for forum access, and the vast majority of the accounts that will lose access are alts or trolls. However, that being said, this will impact some older members that don't frequent these parts as much as they used to. This won't affect me, but there are other users that came here originally for Halo that have drifted away from the games but still maintain their accounts for occasional community contact. I propose a grandfather clause to allow older members who have been on the forums for years to still maintain access for their loyalty. Even if you want to put a join date on it to prevent existing duplicate accounts, five years, seven years whatever it may be, I'll see people every once in a while pop their heads back here after years of absence just to say hi. Many of them have moved on from this place, but it's always good to see an old face and remember the people that helped build this community to what it currently is. I'm biased as hell, but those people should always be welcome here.
