Monthly Meetings

The Saint Louis MO, STL Linux Users Group (STLLLUG) meets monthly to learn and talk about Linux. This GNU/Linux Users Group usually holds its meetings on the third Thursday of every month. Meetings are free, public and open to all.

We will continue with our great restaurant location. You can come early, or not; but, we should all wait to order food and drink at the same time.

We start gathering by 6:30PM and at 6:45PM we start with introductions, announcements, current events of interest, and a general CALL FOR HELP segment. Then we will go into the presentation of our main topic, sometime around or after 7:00PM.
