I recently received an email informing me of the IBM Users Group of Central Missouri, CMIBMUG, who meet in Ashland. Ashland was chosen as the host city as it is midway between Columbia and Jefferson City.
You can check their website at cmibmug.org.
This link has been added to the IBM i user groups page. You will find a link to the user groups page at the top of every page of this website.
Check out which user group is closest to you.
If you know of a group which is not on the list use the Contact form, on right, to send me its details.
