Welcome, you guys - We're very glad to have you!
PIF Silvergate is not only one of the oldest guilds in WoW (We formed on Icecrown immediately after the game launched) but one of the oldest continuously running gaming guilds in the world, having officially been around since 1999, and unofficially as far back as 1992. Back in 1992 there wasn't really even a such thing as a "gaming guild"!
So, in short, you've found yourself a great community of people and I'm sure that you'll all be happy here. I look forward to getting to know you guys here on the forums.
