http://www.oakden.org/mark has more detail about me than ANYONE would really want to know.
I have written an emacs mode for communicating with internet chess servers (based on comint and code nicked (with attribution!!) from Gnus). It is described on the ChessMode page. I can be found on the FICS and ICC servers logged in as Sheridan.
I also play at coding in Tcl (which also has a Wiki at http://mini.net/tcl/ )
For a little bit of Emacs/Tcl crossover, see this page (http://mini.net/tcl/EmacsOutlook) at the Tcler’s Wiki. A couple of short Tcl scripts and a bit of Elisp and it is possible to use NTEmacs to edit email messages/replies etc. from Microsoft Outlook!
