IMS has created a discussion forum to discuss IMS Specifications and share experiences between developers implementing IMS Specifications. The form is available to the public. You can join and participate in the forum with a free IMS Community account.

As we go forward implementing real, interoperable specifications in shipping products based on IMS specifications – we need a place to talk and stay coordinated and learn from each other.
I would encourage you to come and join the forum. The forum software does not automatically send out mail unless you subscribe to categories or topics in the forum (under “profiles”). I would suggest you subscribe to the Announcements Category which should be very low volume.

Thanks to Steve Swinsburg, Nuno Fernandes, Noah Botimer, and Matt Jones, I now have shape-shifting poms in my BasicLTI. It can compile in 2.5.x or 2.6.x/2.7.x by changing the version in the parent pom in the top pom.xml in my source tree.
Here are the relevant very well written blog posts:
