Thanks for those links Fuzzy!
Alti, I’m still working through it myself. I’m on the verge of getting to level one! If you haven’t been there in a while, they’ve added lots more challenges as well as achievements to keep you motivated. I’m one away from getting the decathlon achievement (solve 10 successive challenges). I believe Sirenfal is a big proponent of Project Euler and IIRC he asked me what level I was at once. I’m sure he’ll correct me with a few lightning bolts if he disagrees though. 🙂
Also, can we get this stickied?
