I was UKCLE's Information Manager from 2001-06 and have been back looking after the content side of UKCLE's website since March 2008 - from Copenhagen. Beats Coventry, anyway.
I've never actually been to LILAC before, as it was called LILI in my day, but I did set up and manage the LILAC 2009 wiki - it was great to help people use the wiki and also to get so many more papers and reports from the conference itself.
I'm looking forward to taking things a step further for LILAC10, so do get in touch if you have any ideas about using LILACnet.
