------------------------------------------------------------------------------

A lot of things discussed in RollerCoasterTalk are in acronym form. This is because writing "Six Flags Over Texas" several times in a posting is tedious, at best. "SFoT" is much easier to write.  Here are a few of the abbreviations you're likely to see in discussions on RollerCoasterTalk or on other sites.  Originally a derivitive of RRC's, it's now grown and expanded.  Updated 2/14/05
