Hello,
"I might even find the time to participate, especially if the jam time spans the first week of March, or Easter." <--- Oh, the second jam will start six days later(Feb). I hope that you will have time to develop a creative entry for the jam.
"Is there already a jam page here on itch.io?" <--- https://itch.io/jam/jam-for-all-basic-dialects-2
"If so, it would be nice if you linked it on the old jam page, so we all can find it." <--- Don't worry, I have put the URL here( https://rcbasicfans.itch.io/ ) so that visitors are able to find the webpages of all the jams easily. In fact, all the six entrants of the first jam have joined the second jam, yeah. I hope that they will submit ideal entries finally!
