// rf22_server.pde
// -*- mode: C++ -*-
// Example sketch showing how to create a simple messageing server
// with the RH_RF22 class. RH_RF22 class does not provide for addressing or
// reliability, so you should only use RH_RF22  if you do not need the higher
// level messaging abilities.
// It is designed to work with the other example rf22_client
// Tested on Duemilanove, Uno with Sparkfun RFM22 wireless shield
// Tested on Flymaple with sparkfun RFM22 wireless shield
// Tested on ChiKit Uno32 with sparkfun RFM22 wireless shield

I'm a member of Cambridge Makespace (where I live) and London Hackspace (where I used to live). Both spaces are fairly mature and have a reasonable number of members for their available space. At a Makespace new member induction each new member is told that they may have a Really Useful 35L box to store items in (less solvents/flammables). This works really well as they are cheap (~£13), robust and store quite a lot of stuff. We have shelving units in our corridors which take ~15 of these boxes so storing the 200 odd boxes doesn't take up too much room.

However we now have enough members that problems with the system are beginning to show. These seem to be: claiming of permanent workstations, excessive personal storage and large item storage. The first two problems largely seem to be solved with tellings off, we've not progressed to formal disciplinary actions yet. We're currently working on using some unused underfloor 'rooms' as large project sto
