It’s usually just comes down to someone suggesting something and a few others concurring with them. If we already have a next challenge, then the new idea gets pushed out to the next open meeting. i.e. there really isn’t any actual procedure per se. I am not sure, but I don’t think we had a challenge in place yet for Q2.
This should probably got into the Threadjacking thread but one thing we (as a LUG) have gotten away from (and I am guilty of this as well) is people bringing their builds to the quarterly meetings (beyond the Build Challenge). One of the best things about being in the LUG is seeing all of the great creations that other members are working on and have created. That only seems to happen now at events and displays, which is awesome of course. But I love seeing Lego IRL so I am going to try to start bringing a MOC of some sort to each meeting and I encourage others to do the same. 🙂
