System Status
No scheduled downtime
Some of the HOWTOs you'll find describe how to do system administration tasks. You probably won't be able to play around with those in the ACL because you aren't a system administrator there! (If you want to administrate a machine and try some of that stuff, you'll probably want to put Linux on your home computer -- it's free!) However, there are many HOWTOs that you can make use of in the ACL, particularly those in the "Programming" section.
Finally, note that the ACL site does not (yet) synchronize its HOWTOs with those of the TLDP. This means that we might not have the newest HOWTOs, and you may be able to find more recent copies at TLDP.
