Add stories here for things you'd like implemented or fixed (the difference is really just a matter of opinion...) in pbwiki:

• After a successful update, the form should return a redirect to the page, so that refreshing the page in the browser later will not ask "do you want to post the form data again"... which would cause massive data loss if you did.

• Implement locking: When a user hits update, the time of the update is recorded. For the next n minutes (5? 10?) if another user hits update, they are warned that the page is being edited by someone else, and they can choose to back out. When either the time expires or the update happens, clear the lock. If the user tries to save an update after another update has occurred, return to the form (don't lose the user's work), but tell them and refuse to save. They'll have to copy, refresh, edit again, and then manually merge.
