Welcome aboard. I have personally found Wikitree to be very rewarding. You seem to have gotten a great start on here, getting a good deal of your family in.
Keep on exploring Wikitree, and becoming familiar with it. You'll learn more bit by bit. When you ask questions on G2G, under the full question box, you have a space to link a profile to the question. On this question, you could put Van Vleet-125 in the space provided. In the space below that, feel free to put in Tags. The Tags direct the questions to those who are working in that area. You have Tagged this question with Van-Vliet, but you could also Tag it with a location, if you are trying to get help from a particular country or state.
When you have become a little more familiar, look up the Profile Improvement Project, and look at going on The Voyage. On The Voyage, they allocate someone to help you learn how to do things to make your profiles look even better. A part of what they cover, will be to show you how to present sources. We have plenty of flexibility, but it is good to present sources in a way, that other people can then use the sources to help them with their own research. The profile that I worked on, was my ggg grandmother at https://www.wikitree.com/wiki/Rutledge-1842
I've probably put too many pictures in the profile, but it has helped me to learn how to add them.
If you need any help along the way. Feel free to ask more questions, or contact your greeter, or contact other people that you see are active on here. There are many people ready to help. There are also weekly YouTube updates, that anyone is welcome to come and watch. And regular challenges that anyone can participate in.
Enjoy your time.
