As you can see, I've also posted the OD&D monsters, because these are primarily Mystara (and are also in the same special conversion thread).
I've got a few replies so far. At the moment it is the, now typical: "did they see all the conversions at our website" kind of talk! However as there seems to have been a conversion process over at the WotC forums, I think/hope there will be people at The Piazza who want to help out.
(And if BOZ ever says he needs anti-deletionist Wikipedia help with Mystara citations, please point him at this forum.)
