IBM has their own User Group for the IBM i community the IBM i Virtual User Group. Being "virtual" means that we can all be members.
Its home page here.
You can join its mailing list by emailing email@example.com.
They are offering a webinar on Wednesday November 13th at 10:00 AM - 11:00 US central time called "Modern RPG - a look at the NEW and Improved Free From and other Modernization thoughts".
For this session we will take a look at the new free form updates that have just been announced with TR7. RPG has continued in its march to be a modern business language. We will look at the updates to the language and the tooling for creating new code in a modern manner along with tools that can be leveraged to help you convert your existing RPG code in a quick and accurate manner.
