There are different means to get in touch with us: Sending a mail to info@c3l.lu or over at Mastodon: @c3l@social.c3l.lu. Press & Media should use press@c3l.lu and see the press page. Please note that we are all doing voluntary work here. Do not expect immediate responses! There are simply no office hours. Secondly, we are not a computer repair shop. Don't contact us to ask if we can fix your computer. Also read this FAQ, before contacting us.

You can also visit us in our hackerspace ChaosStuff. See also our Guidelines.

We have a publicly-available Channel on our XMPP and Matrix server. Everyone is welcome to join and chat with us:

Since 2008 C3L tries to raise a awareness for privacy and the fact of having a transparent government, instead of a transparent citizen. It's hard and rock way.

Here, in Eire, the NGO Digital Rights Ireland, organized a conference about privacy, data protection and data security in general.

The schedule is quite busy and parallel talks seem to be the normal way of procedure as well.
