This week I came across the web site for the Mid-Range Michiana Users Group, MRMUG, of northern Indiana. Their president, Craig Nelson, informed me that they meet monthly in Mishawaka, which is part of the South Bend metropolis.
You can check their website at mrmug.org.
I have also added this link 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.
Feel free to check out which user group is closest to you.
If you know of a group which is not on the user groups page use the Contact form, on right, to send me its details.
