Hey, Bob! :-)
I think you and I ran into each other yesterday during my Ranger shift. Seems like we talked about triangles! ;-)
As a Leader, myself, I assure you that I would not be upset with anyone editing one of the profiles I manage as long as they're doing it constructively. I welcome it! ;-) There's so much work to be done here, that I think we can all use all the help we can get.
I'd like to encourage you to get involved in some of the projects here on Wikitree. One you might be interested in is the Profile Improvement project. This project uses the many Maintenance Categories that have been set up to flag profiles that need sources, GEDCOM clean up, biographies, etc. It's a really great way to get to know other members on Wikitree, and it will also help you get proficient with using wiki markup, categories, in-line citations and all the other fun things that you'll need if you're interested in working on pre-1500 profiles.
Working with these earlier ancestors requires some special knowledge -- where to find sources; how to discern a good source from a not-so-good one; how to properly cite sources; how to search for duplicates; how to format names according to the standards that have been developed, etc. This is why we ask for people to work just a little harder to learn Wikitree before they start editing these profiles.
Something you might not know is that ALL of us -- Leaders included -- had to go through the application process. It's not an automatic thing for anyone.
I guess what I'm really trying to say with all of this is that the opportunities on Wikitree are open to everyone, and we want you to succeed. Also, as a rule, we try to assume good intentions were meant when someone edits one of the profiles we manage. I don't think any one of us would claim to be perfect -- we've all made mistakes and have been graciously forgiven. (thank heavens!)
I'm sure I'm not the only one who will offer you an "open door" if you have questions about anything. Most of us here love to help! :-)
Please feel free to message me any time!
