I am delighted to meet you! I started here less than a year ago with far less knowledge of genealogy than you now have - I just thought you write what you know about your ancestors - more like anecdotes about your interactions with them and then for the ones who were too many generations back for you to have known them, its anecdotes about their interactions with each other. The word "gedcom" sent me off on my first learning curve and you already know aobut that, as well as the fact that there are sourcing standards - seems to me you're way ahead of where I started out!
All I can say is that you have come to the most right place there is - I have found all the help I needed here, from people who are as supportive as they are knowledgeable about genealogy. They have not only tolerated me, but also educated me (and still are) and there are at least a couple of dozen who I now think of as not only mentors but friends.
Welcome to WikiTree - feel free to ask anything here - you'll get an answer very quickly because there are so many people who know so much and love to help others! Everything you see written here about collaboration is for real - the main thing we do here is to work together!!!
