If nobody has published a Game Courier chess variant problem in almost 10 years maybe the editors will take notice of it and try to repurpose this feature.
What is it you have in mind?
There are great chess variants that are not on Game Courier, such as my own Scramble that could be played against Stockfish and could generate lots of problems to be published.
Game Courier has nothing to do with Stockfish, though. So, it's not clear how this ties in with what you were previously saying.
Another purpose/feature would be to show updates from members' own YouTube channel/ or social media pages where they talk about chess variants and chess variants problems.
That's also unrelated to Game Courier. If members want to, they can already put information about YouTube channels or social media on their profile pages, and they can post to their profile pages to keep people up-to-date on videos or other Chess variant related things they might find interesting.
