In late August, Kim Thomsen from the LEGO CEE Community Support team contacted myself and the Eurobricks team with a challenge. They are impressed with the database of alternate build MOCs that Rebrickable has accumulated and wanted to see what the community could come up with under some quite restricted conditions. These conditions just so happened to be similar to those forced on internal LEGO designers :)
There were a huge number of small fixes and tweaks made in the last month, but no really big user features. I mostly concentrated on fixing known problems and tweaking existing features. I also spent some time beefing up the tools used by the admin team to make their life easier.
