Here in G2G as you formulate your question, the text box contains tools for formatting. One of them looks like a link. You can highlight text, click on the link and a window comes up to insert the URL. You can and should if the question is about an existing profile, type the Wikitree-ID in the text box labled "WikiTree ID/URL if this relates to a person or free-space profile"
Your concept of privacy levels sounds logical and reasonable.
Two suggestions on the profiles:
I love the narratives. Not so long that I got bored, but with lots of interesting tales. You can come write bios for Collaborative Profile of the Week anytime. (Shameless advertising). But I would add a source for the narrative just to make it clear where the information came from. Something like "Life stories told to Michael Smith by his father Smith and/or grandfather Smith and personal memories of Michael Smith."
The other suggestion is to beef up the information in your other sources. For instance 1920 United States Census Census: Town, Fremont County Wyoming (I know you have it listed at the top of the page, but it belongs as part of the source citation also) Instead of "Mentioned in family obituary, Albia Republican", tell me whose obit, Albia Republican, town and state of newspaper and the date. Birth Death and Marriage Certificates should have who, what, where, when. As a general rule remember that journalism mantra "Who, What, Where, When, Why and How (not neccessarily in that order). The Why and How are not always important in Genealogy, but the first four are essential to sourcing. Wikitree Help page on Sourcing
Overall a very nice pair of profiles. Thank you.
