I've been searching for a blog that not only lists all the challenges out there but also what the current challenge is and just haven't been able to find one so I've created my dream challenge blog to keep track of them myself!
Here is a link if anyone is interested in checking it out:

Please note that my goal isn't to list any and all challenges out there but rather to list only those I'm interested in participating in after reading the rules to determine if it is a challenge blog that fits my style of stamping.
Enjoy!
