Oh, Rebecca, I beg to differ with you. You ARE TOO a genealogist - namely, a person with an interest in genealogy. If you did not have any interest in genealogy, you would not have joined WikiTree. Obviously, there are different levels of genealogists, ranging from just starting to pursue their own family history to professionals who charge for applying their considerable expertise to research problems that other genealogists found unsolvable.
WikiTree names its membership levels as guest, family member, and Wiki genealogist. These, too, have nothing to do with the level of expertise of the members, but only with their interest in using the WikiTree website. WikiTree welcomes everyone, but because we have one single tree here for everyone to share, it is necessary to protect the data from inaccurate or undocumented changes made by people who either don't understand what we're all about or don't know enough about what they're doing or - it pains me to say - the rare case of someone who wants to deliberately vandalize the data that is here.
When someone signs up to join, they are designated a guest member. This level has pretty strict limits on what they can see and do on WikiTree. It doesn't matter how much they do or don't know about genealogy - the only thing that matters is how well they understand what WikiTree is about. A guest member is free to upgrade to a family member at will, but they will have been presented with enough information about WikiTree to be trusted to work on their own family. When a family member signs the Honor Code, they are officially designated a wiki genealogist and are then able to edit all profiles that have open privacy, in order to contribute to our tree of over two million profiles.
By asking this question, you have clearly demonstrated your understanding of the responsibilities of full members - those designated "wiki genealogists". Now, go forth and increase your experience ... whenever you have a question, feel free to ask here. With many thousands of members all over the world who have widely varying areas of expertise, someone is sure to be able to provide the answer and, when that happens, your experience will have just had an increment. Before you know it, you'll see questions that you can answer. You are now part of (what I have found to be) an incredible community of knowledgeable and caring people - I'm thrilled to welcome you here!
