There are exhaustive lists of DOs and DON'Ts available elsewhere, but for the most part they are all just common courtesy. Likewise, responding to 'flames' usually merely incite more, and are a waste of the networks' bandwidth. Generally, short ads posted infrequently are tolerated on the list. A URL in the listing pointing to more detailed information is also preferable. Entries are stored in a database and can be searched on by region, job type, and keywords.
Old listings are automatically removed and posters can delete their own postings once filled.
In addition, there is also an area to post resumes on this site. Also, Interex maintains several other mailing lists related to HP3000 vendors, solutions, and special interest groups. Click here to go to Interex's web page where you can sign up for them.
