I’m having some experiences at playing with the C64 Club Berlin homepage at https://c64clubberlin.de
You may ignore or watch closely while some minor glitches may occur. But don’t panic. Grab your towel. It’s always good to have one these days.
In any case of doubt feel free to give advice at freenode #c64clubgames anytime you like, because we have Lamb3, a nice doggy with note function. Try .note send TuB your homepage is faulty or something else. Thanks!
