I forgot to mention that "write note" is now "write comment" and moved from the visit page to the waymark details page alongside "visit waymark". I guess simple edits will be made in comments by anyone too squeamish about editing someone else's waymark.
Another idea we have for notifying waymark owners of edits to their waymark is to have the site automatically post a comment to the page showing the old text vs. new text. This would generate the typical log notification you already get, and be a way for those not involved in the process to see what is taking place.
Anyway, hang with us and try to be optimistic. The release begins in 5-10 mins.
