Genealogy Links

Well for the most part today, I have been on Facebook connecting with people with interest or related with some of the surnames that I am researching.  I have also been joining several helpful facebook groups and saving helpful webpages as bookmarks.  I have had major problems in the past with looking at member trees on ancestry and making major mistakes on my own tree.  Now I have a thing to where if I do not have a source then it does not go on there.  Of course, this is a major genealogy thing anyway.  I just want to do this the right way, and make sure that every name I add has sources.  I would rather have 20 people in my tree and it be right then have 2,000 and it all be wrong.
