For those who are interested in a LTC (local or UK) and who cannot attend
the meeting on 19th January, can we please have any comments/suggestions on
the following by 18th January as we intend to finalise design standards etc.
You input is essential - it will be 100% better if we adopt a standard that
everyone can use for (dare I suggest it) future 'national' meetings with a
large integrated layout.
Many thanks,
Jon
