When you need to know something, you can ask your fellow subscribers. If you know the answer to someone elses question, respond to the message. To provide information to all others in the group, send a message to the group. The list processor takes care of distributing it to the other subscribers of the list. This is a new list.
Volume is still negligible.
The list is targeted at a specific audience, those developing Web applications using Oracle, and also enables those without Usenet access the ability to benefit from shared Oracle user information. However, some users may have to pay for email messages originating outside of their system. This is the case with CompuServe for example, where Internet messages cost about 10 or 20 cents each. CompuServe users may be better served by using the Usenet newsgroup comp.databases.oracle instead. Make sure you supress your signature lines if they are normally added automatically.
