1. APPEND BLANK shouldn't create abnormal multiuser problems. The bad thing here that users will create too many unnecessary records (if selecting Undo during entry).
2. It entirely depends on app design. If you decided to use buffering, use it everywhere, if not- abstain where possible.
3. Yes, VFP will handle locking automatically. Actually the purpose of explicit locking or buffering is to inform users that someone else working on the same record and handle this case in more sophisticated way.
