A few nice additions, using the internet would be: a regular e-mail newsletter, including information such as current prices of rental, fuel, landing, hangarage and also events and information which would affect flying. E-mails reminding expiry of medical, license etc.
Also would be good to have access online to the aircraft POH (not sure if thats copyright though), online booking facility, list of aerodromes which have reciprocal landing agreements, Flying Order Manual, prices, opening hours, events etc.
