A lot has to do with the moderator,my two favorite recent ones were "Steel Cats" by Tigerman Eric and "The Panzer III Build" by DeafPanzer Andy,Now those had a lot of encouragement and most important,completed builds,and the Moderator not loosing interest.
You are very right there. Mustang is another example, his GB is still going great guns. But sometimes, no matter how hard the moderator tries, a GB simply goes now where. I think we not only need to think about what GB's we are starting, but also think about those we are joining and are we really able to commit to it.
