The TDM New Mapper's Workshop will be beginning in about a week (if there is sufficient interest).
I have about three months before my free time starts to decline, so my intention is to run a short workshop that fits into that time period. Missions will therefore be small (which should always be the case for first missions anyway), and we will aim to complete them by September.
I need to restate that this is a beginner's tutorial. If you have already mapped for TDM, even if you've never finished and released your mission, you will probably find the early lessons a bit tedious.
The format would be me preparing and releasing a video lesson, which particpants can follow at their own pace. We will have a forum thread open for any questions, and for sharing achievements as we go. The videos will continue to be useful after the fact, and should make doing this again much easier. My schedule doesn't really allow me to conduct live sessions, and I'm not sure that's very useful in a mapping environment anyway.
I'd release a new lesson each week or two, and we'd encourage everyone to keep up with the lessons if possible, showing off our efforts before moving on to the next step. Those participants who complete their mission by the end of the workshop (or reasonably close to it) will recieve a small token of their achievement by mail (not to mention receiving the excitement of TDM players with new missions to play)!
If you are interested, haven't mapped for TDM before, and are able to participate in the next three months, please sign up here. I'll PM you some questions about what would be the most useful format for you.
I'd like to get the workshop started in about a week's time if we have enough people.
