I don’t know what LEPIN is.
Knockoff brick brand, blatantly stealing both TLG and AFOLs’ ideas. It was mentioned quite a lot at the fan weekend. People in the community hate them. Because they’re evil.
Here’s a letter from someone whose work was stolen: http://www.brickfanatics.co.uk/an-open-letter-to-lepin-from-a-frustrated-lego-builder/ (This actually includes a few comments about the resale market, too, which are worth noting…)
All that said, and LMGTFY joke aside, I fully agree with the “starting with forgiveness” and with “This is not conduct Steel City LUG condones, and I expect the same ethical and moral standard to be upheld by Steel City LUG members” as our policy moving forward.
