I think we all are guilty in this. Half-finished models hidden in boxes, collecting dust, waiting to be worthy for our attention again. We left them, because we lost interest, lost parts, the kit proved to be too difficult, or too badly engineered... there are many reasons. Here's the chance to give them justice -and learn in the process.
The Rules and Regs
Any started kit, even unstarted ones if the reaction was "oh, boy, I hope I can sell this on EBay" upon opening the box. Use the forums to record and discuss the build, so we all can learn.
The more kits you finish, the better :) Tanks, ships, figures, aircraft, any model kits are fair game.
