UNIX accounts have a cpu limit set at 15 minutes to stop runaway jobs. You have to do this each time you login to override the default cpu limit, so you should add a line to your .login or .mylogin file. Make sure you give yourself a reasonable time limit. While there is no limit set for diskspace use, there is a specific use for the computer account and disk space used for non-academic activity should be avoided.
Every user can create their own web page but there are limits to what is acceptable.
ECF also sets a printer paper quota.
