Forum site based on blogger platform

[Bob253builder09]

I have been searching for a Blogger-based forum theme for a while now, but besides the websites https://birforum.blogspot.com/ and https://hersheyforum.blogspot.com/, I couldn't find anything else. It seems like these two sites are not perfectly organized, or maybe this is the best it gets. Does anyone know of another Blogger forum theme or can someone enhance these themes further? Please indicate your fee along with examples if possible. Thank you.
