I have to totally agree with Frank Portella here...
These "little models" take much longer than any kind of models (imho) and a modeler that never built one, can't experience the real fun that is making a real masterpiece, no matter the medium, scale or theme.
I think that with DDD2, the sixth Warship Campaign in Armorama (now MSW), we have reached an optimal time span for a campaign - preciselly one year! Although this was set on a completely different base - honouring Garry Beebe starting and ending a submarine Campaign on the day of his departure.
As some of other members here, my modeling time is not as much as I would like to...

but I have been successfully been abble to finish my entries and maintaining a good level of work done - and I guess that this should be the most important thing in a Campaign: Accomplish the built of one model related with the theme of the Campaign, with good quality!
We are here as a community and the main basis for it is to learn, teach, share experiences, knowledge, sources and resources and also, of course, to have fun. I know that accomplish all this is a little difficult , but not impossible!!!
If everyone gives his/her best, I am sure we will get there!
The keel is laid, let's start building this Ship
