I've initialized the Wiki page for the centennaire Esch (mostly
copy-pasted from the LinuxFest page, minus the stuff that's not
applicable, plus the stuff that was in the mails)
http://www.lilux.lu/wiki/index.php/CentennaireEsch
Please have a look at it, and complete/correct the information if needed.
Also, remember to register as a volunteer. Indeed, I myself can only be
there on Saturday 21st, as on Sunday 22nd I'm leaving for a business
trip in the early afternoon.
Regards,
Alain
