From what I can remember offhand I've had regular contact with Jim Beaver, Traci Dinwiddie and AJ Buckley (all have been in Supernatural). Also various cast and crew from Horrible Histories pretty regularly. I've had a DM from the wonderful George Takei (ooooh myyyyyyy). Dame Tanni Grey-Thompson, an icon of mine, once tweeted ABOUT me, not directly to me, that I was 'a genius'
. Made my day.
