I know exactly what you mean about being intimidated by this place. I joined in 2008.. and finally posted in 2011.. LOL.
Personally.. I love the old grid style maps. I still play a MUD off and on to this day.. so seeing little squares representing blacksmith shops, taverns or stores, is like seeing an old friend. If you need help just ask.. most of the folks around here are very friendly and helpful. There's a great Tutorial/How-to folder in the Mapping Resources section of the forum as well.
