In case you have not noticed yet Wizards of the Coast are due to delete their forums on October 29, 2015, at 10:00 a.m. PT. Everything in the Mystara forum will be deleted on that date. Wizards of the Coast are asking for you to move your content.
There is a ton of awesome stuff here. It would be a shame to loose it all. 
The Piazza is offering an open invitation to all Dungeons & Dragons fans.
Please help The Piazza save the best Mystara forum content by crossposting it to the Mystara forum at The Piazza.
I have a sticky topic up at the Mystara forum at The Piazza: Please archive content from the Mystara forum at WotC. It has more detailed instructions on how to move stuff.
Please help save Mystara content if you can.
