Real Life Meetings
There is an Ubuntu LoCo meeting every first Thursday of a month (with possible exceptions) at the Stampfenbachstrasse 69, Zurich, ID-Lounge / E Floor. If you are planning to attend, please take a look at this page for exact dates.
There is also a monthly Debian meeting in Zurich which might be of your interest.
At the moment no IRC meetings are planned. You can of course always join #ubuntu-ch on irc.freenode.net to meet other LoCo team members.
