Be Bold is the main theory that makes wiki editing work. If you think a change will improve things, make it.
Just remember that the companion to 'Be Bold' is 'Be tolerant'; someone might have a different opinion. If you are that person who has a different opinion, express it, either on the talk page or in the summary comment, if it's short enough.
Remember the old Fidonet mantra:
- Be ye not overly annoying, nor too easily annoyed.
Assume Good Faith, and most problems can be overcome.
