It just so happens that this same question came up about a month ago. A search of the archives should result in some useful information. Try using Yucatan or Maya as a search item. My last message on this topic is #22144. In an effort to conserve space on the archives, instead of reposting my message to the group-at-large I'll forward it to you privately.

The archives are an amazing resource and can be quite useful.
