As a Guild Leader, I absolutely agree with the points she puts forth, and I recommend this list to any guild officer, especially those that are just getting started with their guild. Over the last four years of being a GM, the #1 thing I've learned is that there are absolutely real faces behind those pixels, and you need to know how to interact with those people. You need to get to know them, you need to try and be a little personal with them, and you should know how to talk to them. Everyone is a little bit different.
Most of my guild is very rough and tumble, we can yell at each other and everybody is fine afterwards, no harm done. There are a few people you just need to be more gentle with, though. People you need to talk to in private if there's a problem, make sure life is going okay, all of that sort of thing. You can't treat everyone the same, you need to be able to figure people out.
Being an officer is definitely a job, but I think it's worthwhile. Personally, I think the most important thing to keep in mind as an officer is that you're not above the rest of your guild. You might need to pull rank to stop drama now and then, but you should always remember that they're not just pets to order around in raids. They're your friends, your teammates. Without them, you're really not much at all and might just find yourself on Guildwatch.
Go on, give it a read. The Wordy Warrior is a smart lady.
