Click on the search button on Memmy, type “accidentalrenaissance” in the bar then click to search communities. Both the kbin and the blahzone communities show for me there, pick which one you’d prefer and subscribe. Or both. You can do both.

In Memmy, click “search”, type in the community name, and click “search communities”

The cool thing is you don’t even have to type the whole community name. I was able to just put “accident” as my search and it came up. So click the comm and then click the subscribe button
