May I join please. I have a lot of my profiles that need improving, but, thankfully I added them onto wikitree the hard way rather than using gedcom. I think all my profiles have at least one source, but most of them need more work and biographies adding. I have recently stated joining the Saturday Sourcing Sprints, and using my time on Saturday to work on other peoples unsourced profiles. I also joined this months Biography Builders challenged and have really enjoyed it.
