Good idea - I live 10 minutes from Gatwick, and work in South Harrow at
least 2 days a week...

This kinda makes me recall the discussions a while back about a UKHA
face-to-face meeting...... (which hasn't really got off the ground yet...)

I guess it's now the wrong time of year, with Xmas coming up & all, so
if
it's ever gonna happen, I guess it would have to be in the new year?....

Failing that, the kind of one-off meetings like the kind that could have
happened below (if only the protagonists knew they were just 10 mins away
from each other), could be facilitated if we all knew, or had access to
each
others' private addresses....

I'm willing to publish my details to the list membership, and would be
happy
to receive visitors (not unannounced of course), from list members should
anyone happen to find themselves in London with an hour or two to spare....

What do you all think of this?...If it's a goer, should someone (perhaps
the
list moderator) serve as a central repository for contact details, or would
it be better to just have each individual mail the list with them?

Regards.

Paul Gordon
