Refreshments:
Tea, coffee (instant or real coffee) and hot chocolate can be provided for free.
We usually have a supply of cans of coke & diet coke, and sometimes
bars of chocolate. Cans & chocolate aren't free, though (35p a can,
30p a bar of chocolate).
There's no problem with ordering in pizza or similar.
Ubuntu:
10.04 is due out on 29th April, if you want to do some installs. I'm
running beta 2 on my laptop at the moment, so I'll not be installing
(I'll already have it), but I'll be happy to try & help out others if
they have problems.
