Hi Chip,
As TwistedFate says a group build can be many things. The Spitfire group build that as TwistedFate rightly says is just getting started. If you have any interest at all in aircraft this would be a good one to join. It all started because Roger, Favorisio, expressed a wish to build an aircraft model. He has just started out in modelling and is on, I think his second tank. For an easy straight forward build I suggested the Tamiya 1/48 Spitfire Mk1. Because I'm involved in 2 group builds, building 5 models it isn't planned to start until after the Corsair group build finishes, in May. If you take a look at the Spitfire group build thread you will see that there has been some interesting discussions so far, and they will be on going until the start of the build. When we start the build there will be no time pressure imposed, because remember the idea is to help Roger through the build with as little hassle as possible. We will discus each stage in the forum, or in the chat room then build that stage sorting out any problems, if, they occur. Any level of builder is welcome, the idea being that the more experienced help the less experienced. If you have any questions about this particular group build just ask. :-)
By the way, if you want to join just express your intention on the Spitfire group build thread, there is no pressure and no harm will come to you should you not complete the build
The only thing you have to do is have fun and learn :-)
