1) Cyberpatrol. Easy to use once it is set-up. Actually the set-up
is not that tough either. Primary reason for it is that I can restrict
the amount of time they have access to the internet on a per day basis,
as well as hours of access to the internet (for example from 6:15 p.m.
to 6:45 p.m. ONLY each day....or different hours for different days of
the week). As well as set weekly limits.

CP also allow you to filter/block websites, block kids from giving out
information (street names, phone numbers, etc.).

It also allows quick overrides, etc. Check out google if you want to
find the program.

2) PC Tattletale. This is a big dog spyware program. It can monitor
everything from exact keystrokes to e-mails, programs run, windows
open. It captures screenshots, Records IM and chat, etc.
