Yeah, this is an ugly page. It's just to provide a download link for the Firan ADM dictionary file; this adds 'Ranivor' and 'Shamibelian' and other common words to the SimpleMU spellchecker.
For registered SimpleMU users, you can download this file and place it into your SimpleMU directory. Then you can go to 'Configure Spell Engine' (under tools) and select 'Locate Dictionaries'. Select the SimpleMU directory in the browse window, and then 'firan.adm' should appear in your list of options. Select it in addition to American.adm (or whatever dictionary you are using).
Right click on the link below to download!
