Hi Wildcats18, welcome to the forum.
The beginners session is a great place to start, but if you’ve played inline you may not need a lot of what’s taught there.
Currently, casual games are being run on sunday evenings (I believe). These are pretty relaxed, and are organised week to week by Graham Phipps-Black (username “Active”). Not sure what time, sorry, but hopefully GPB will stop by this thread to let you know.
We also usually run a local league (the DIHL) but as of now no final plans have been made for the running of the competition this year. Hopefully by the time you get here that should be sorted out, so keep an eye on these forums.
And to answer your other question: Yes, you’ll be playing with guys . Don’t worry, most hockey here is non-checking.
Cheers,
Chris
