I'm up for one. But since Carmen isn't one major show plus source material, appearances tables would vary by the medium/incarnation. TV shows like 2019 characters, for instance, would probably get two navboxes of both seasons and perhaps for chapter books, and the game shows get their seasons, too. As for game-exclusive characters, they would probably get their appearances based on installment rather than episode.
Around 447, I believe. However, many of them were random blog posts or jibberish. For instance, one was on a "list of third-graders", while some were seemingly on games, but all the content that was on them were non-sequitur statements. Incidentally, they seem to have all been by someone who was using the same account more than once, given how similar the edits were.
I was indecisive about what the new logo should be, so I left it as is until a good design could be found (sorry about that, totally wasn't intended to be the final one). I love this logo idea you cane up with though, the lettering especially! Do you have the link to it that I can use to add?
