I keep posting questions about challenges that I am sure have been asked before. I assume each challenge has its own page that has all the forum posts that have been asked about it, but I can’t find such pages.
no, each user is encouraged to use the forum search, or to open their own thread for a challenge using the Ask for Help button
Nope, but the forum search works really well. Doing a couple quick searches will often get you to some very similar questions.
