Short VersionPoliteness and manners are a requirement to participate in the Sveasoft forums. If you express your opinions in a well-mannered, thoughtful way your contributions will add to the general knowledge base and will not be edited, deleted, changed or modified in any way.
Long Version
No user of the site has any right to post anything they feel like posting just because they are registered. Though rarely done, posts can be edited for clarity, brevity or any other reason deemed appropriate at any time.
Any poster who flames others is not posting according to the rules. Similarly, any poster who "trolls" is by definition trying to induce flames by others and is guilty of flaming by proxy. Neither is allowed here.
The discussion of "warez" or "cracks" or the "how to" of stealing service, bandwidth, etc. is not allowed on the site. Period.
Do not take it upon yourself to point out where other members do not follow guidelines because that leads to more off topic posts and public arguments. Send the admin a private message instead and let them know there is a problem.
Posting off-topic, or against the letter or spirit of the forum description, is not posting according to the rules.
Any poster who sends obscene, threatening, or insulting messages to any other users of the site is not posting according to the rules.
Any poster may be banned at any time by name, IP address, or other identification without prior warning and without explanation given. Banning is an exceedingly rare occurence.
