Okay, so we've done some minor surgery and tests on the Scenario-Wiki, and the only hitch is that each person has to be "invited" to join, in order to access the features. This is a pain, and I can't do it myself, given all the other emails and posts I'm answering at the moment, so the Valiant Tod Creasey has volunteered to co-own and let you guys into the sandbox.
Some of you know Tod from his many Grande Armée and Might & Reason scenarios, so he seemed like the perfect guy for the job.
Here's what you need to do: Just post on this thread by listing your email address - that's it. Tod will then invite you, and you can use the Wiki.
