1. CUHK newsgroups are created not only for campus events discussion, but it is also a free forum for ideas and opinions of topics related to the University. Some newsgroups are also dedicated for specific purposes (course discussion or announcement). Any posting outside the specified scope is not allowed.

It is regarded as a serious infraction of ITSC policy and will result in temporary, THREE months, or permanent loss of ITSCnet access privilege as documented in 9.2.3 of "Computer Network - Policies and Guidelines on Access and Usage.

However, for public interest, the ITSC will cancel postings which carry worms/viruses or postings which are regarded as harassment. Accordingly, such cancellation will be announced on the corresponding forum to update the readers.

8. Crossposting is a feature of Usenet and it is useful to post articles which are related to different topics. However, this feature is sometimes abused. Articles with irrelevant topics maybe crossposted to a large number of newsgroups. Modern news servers often have filters to filter out articles abusively crossposted.
In the University, cuhk.* are supposed to be propagated between news servers in CUHK. However, most of articles posted by outsiders were with unrelated topics. Starting from Jan 18 1999, the cross-posting to cuhk.* newsgroups from non-CUHK servers were prohibited. The articles can still be read from other non-cuhk.* newsgroups if they are cross-posted to.

9. When posting to a newsgroup, please ensure that your computer clock is correctly set so that other readers can follow your posting easily. The ITSC will warn or discipline users who deliberately set their clocks forward significantly (e.g. more than 15 minutes) without good reasons, because such a practice is a nuisance to many readers who want to read the latest Usenet articles.
