As I mentioned earlier this year, 2002 marks the 10th anniversary 
for Sys Admin magazine. Through the years, the magazine has addressed 
the systems administration demands of heterogeneous environments while 
weathering challenges in the high-tech publishing industry. During its 
10-year evolution, Sys Admin has provided regular coverage of Security, 
Open Source, and Perl, along with many other topics. Sys Admin also 
acquired The Perl Journal, which is now produced as a quarterly 
supplement, and relaunched as a UNIX-centric site 
presenting book and product reviews, certification updates, and 
Thanks to all our readers for making Sys Admin a success. Let us know 
what we can do to make it even better.
