Hello,
An overriding concern in the community, as regards who should be able to edit in Wikipedia, appears to me to be the avoidance of elitism. I strongly agree.
The strong concern I have with editing in Wikipedia is the accountability of the editor. If a person joins a community they are accountable to that community as well as to anyone that community effects. And, simply because a person is a volunteer¹ on a project does not mean they should be held to any lesser standard than one who is not.
I believe anyone who wishes to make edits to Wikipedia should have a single, individual, registered User Name, User Page and a Talk Page. With this, anytime a person makes an edit, creates a change, in the encyclopedia, their User Name is recorded with that edit. Accountability. Trackability.
Presenting to the confidentiality concerns: There should be no requirement as to content on the User Pages they can be blank if desired. What matters is the accountability & trackability of that editor.
