Irelc/Baar/Baars etc. - A very very nice person who has set up so many adept raids. He has dedicated so much time to this game for others. Sure, he has gained xp and loot along the way, but he has helped so many more folks in the meantime.
Grinkles - Everyone has said it. The Grinkles Army is such a great idea and he has put so much effort into it. Also, if you want to find a list of helpful folks, look at the names he has chosen to name the army after. There are some great folks on that list. Even before the adept project I found Grinkles to be very thoughtful and kind. A wonderful person.
Matbar - A true tradeskill giant. One of only a handful of folks to complete all the tradeskills and she is my favorite. She has never been selfish (to my knowledge) when it comes to finding recipes and sharing them to further help tradeskillers. She is one of my all time favorite people to talk to.
Tamlissa/ Kerolynne - Yes, I know she can rub some people the wrong way. But, I have found her to be incredibly generous. She remains in DB and offers her goods and shares knowledge with new people constantly. She has donated hundreds of maps to people to get them started on treasure hunting fun. She knows this game and the rules and helps people to stay on the right path. She is a tremendously helpful person and an incredible member of the community.
