Well, it looks like I was able to restore the original one to my page to preserve it and the comments. Thanks for the tips on organizing my MOC's into folders. Once I have some more I will definitely do that.
Yeah I would it was your most popoular moc from memory. Although this is a 'better' moc it might not do so well. You could always remove from a group if you are worried, but i think it will be fine. When you have a few more mocs you can organise them into folders (on your homepage). I do this as soon as possible so people can see lots of my creations (not only the most recent 6) on my homepage - shamless self promotion ;). Will your wife be posting any mocs?
You have deleted the other one and all your comments :(. Oh well I get to comment all over again :). It is an improvement, the lights and rear mudguards are much better. Keep 'em coming. I bet the sonic boom will be a real challenge to build an alternative with, i can't wait to see what you come up with. Good luck
