All individuals affiliated with CREN Member or Affiliate organizations are responsible for seeing that their communities are aware of these guidelines, and that the guidelines are followed, both in letter and in spirit. CREN networks are, at the discretion of the institutions involved, open to use by students enrolled at participating CREN Member or Affiliate educational institutions. The following examples may help users of the networks apply these principles in particular cases. Messages that are likely to result in the loss of recipients' work or systems are prohibited.
Advertising is forbidden.
Discussion of a product's relative advantages and disadvantages by users of the product is encouraged. Vendors may respond to questions about their products as long as the responses are not in the nature of advertising. Any communication which violates applicable laws and regulations is not allowed. Users are requested to minimize the transmission of large files in order not to degrade network performance. Files up to 1 MB should be able to traverse most of the network.
