I was very (very!) disappointed to be unable to attend the
January meeting, due to the sudden onset of a head cold.
[BTW, whenever you intend to present this again, perhaps at a
neighbouring LUG, please let the list know - I'd probably even be
willing to travel to catch it after having missed this one.]
By any chance, could you expand on some of the points Charles has
very kindly posted? [Other readers, if interested, please also
encourage John here.]

Other questions:

Do you have a favourite first, K.I.S.S., site for a new person to
go to to get up and running quickly and simply to start to get an
initial handle on what the heck this stuff is all about? There
appear to be many, many, sites out these days, and it can be
daunting to first encounter the more deeply technical ones. Do
you have a favourite?
I see a number of hardware products out there which appear to be
provider specific. e.g. Skype, Vonage. Does it actually matter?
(When intending an Unlimitel account, say.)
In an earlier list thread, I posted:

I don't remember seeing a response. Perhaps I missed it?
