And, I need to thank some people :
hespa for being awesome and picking up himabindu and friends from the train station, and hespa and toley_elf for making shortbread and vegetarian haggis(!) for us.
emilly (aka celuran) for also being awesome and taking my co-workers safely back home afterwards.
rwrylsin for organising so much of the party - lots of yummy food (Jaffa cakes ! Irn Bru ! Edinburgh Rock !), decorations, balloons, etc - you're awesome too :-)
And also everyone who came along and helped make it a good night - thanks !
