The TLK-L member directory aims to be the official directory for all members of the TLK mailing list. It is mostly automated, which means that adding and removing of records is done without the need for an active maintainer. Of course, there's still Zazu who watches over it and makes sure that everything is in order.
If you experience problems with the directory, or if you have any comments or suggestions, please feel free to write a mail to the maintainer.
