In-active commish

I'm in a good league and we have a commish that is inactive. He hasnt been on in a long time, I think since we had our draft. We all have sent several messages to him and he hasnt replied to any of us. We have all clicked on the clock to remind him as well. We would like to keep the league going and would like to pick another commish from the league to run it. Is there anything we can do? Thanks

The league ID is 122445
