The people @ ENOSIG is intended for the discussion of FLOSS software related to the Eindhoven area. More to the point, ENOSIG meetups tend to be announced here. The list is Dutch-spoken, but English is widely understood, and discussions will generally switch to English if necessary.
The list is low-volume; it averages around three messages per month. Mail from people who are not subscribed is screened first; this ensures no spam will get through.
You can send an email to the address ["people" in the enosig.org domain]. Keep in mind that all mail sent to the list is also made available in the email archive for public reference. Where possible, Email addresses mentioned will be made unrecognisable, names will not.
You can subscribe by sending email to the address ["people+subscribe" in the enosig.org domain]. Note that the plus sign in that address is important. The mailing list is managed by mlmmj, which is, of course, open source software.
If you wish to contact the ENOSIG organisation without publishing this on the mailing list for all to see, feel free to send mail to ["info" in the enosig.org domain].
