@ Bill Vincent -- you are more than welcome to join in and nominate people for future themes for the Connection Finder. Abby doesn't work in a vacuum - she relies heavily on names we, the people, suggest to her. Such names must have a profile image (or one must be findable), and MUST be Connected to the main Tree (I can't tell you how many names I did not nominate because of the lack of Connection, and my perception of how difficult it most likely would be to Connect them in the time). They should also have a decent biography, if possible (although we have featured the occasional profile with little to no biography).
You are also more than welcome to add "appropriate" categories to any profile. If that is not possible due to Living status, then you can leave a comment for the Project managing the profile.
Also -- Categories don't just magically happen because you want them. Someone needs to create them (and we're told there is a very small group of those doing this work), and often they first need to be requested. Nobody is going to create a category on the off-chance it might be wanted some day.
I apologise in advance if I offend anyone, or appear as impolite. My words are not intended to have that effect.
