William, Thank you for at least trying out WikiTree. I know that it is not for everyone but your knowledge would be a great deal of help in filling out the tree, not only for your self but also for those family members who may find it later. If the finding and formatting of sources is a problem for you, I know it can be a daunting task, you could always ask for help. as mentioned above we have a Mentor program with members who are willing to help and there are a lot of us who enjoy finding and adding sources to profiles as well.
Again if you want to leave thank you for at least giving us a chance but we will feel the loss.
