Good Netkeeping Seal of Approval

The Good NetKeeping Seal of Approval or GNKSA is a designation that indicates a piece of Usenet newsreader (client) software meets a set of usability and formatting standards. The name is a play on the "Good Housekeeping Seal of Approval", a set of consumer reports issued by Good Housekeeping Magazine.

The original GNKSA author thought that many newbies to Usenet posted malformed or inappropriately-sent articles because their software did not encourage better netiquette. For instance, software which made it easy to confuse replying to a sender by email with posting a followup to a newsgroup led to users mistakenly publishing what was intended to be a private response, or vice versa.

Some of the guidelines from GNKSA 2.0 are:
 * The user can see the essential header fields, including "Newsgroups" and "Followup-To".
 * The user can edit all header fields when composing a followup.
 * There is a clear difference between 'followup' and 'reply'.
 * Followups preserve the Subject and References of the original article, unless the user explicitly changes them.
 * News software respects "Followup-To" and "Reply-To" specifications.
 * What the user writes is what gets posted, as is.

Additional requirements concern accurate  headers, signature block formatting, and the ability to cancel and supersede articles.
