I have been in the progress of organising a KDE booth at the Linux Expo in London on the 4th/5th July 2001. I have some more good news in that we will also have a booth at the Linux Expo in Birmingham, at the NEC on 12th/13th September.
If you are interested in helping, visiting or funding (yes we need some funding!), please see the website I have mocked up here. Included are details on a proposed KDE Usability Study. Update: 03/19 02:08 AM by N: A new mailing list has been created for people wishing to get involved in the KDE Usability Study.
