Before writing

• Make sure you know what you're talking about.
• If you have to include something off-topic, keep it to a minimum.
• Don't shitpost for the sake of shitposting.
• Actually read the existing replies first, no need to repeat things.

While writing

• Don't just hit the quote button and start typing. Try to edit the quote so that only important information are contained within.
• When quoting, remove the BBCode (like [img][/img]) around embedded images/videos.
• If you don't care for slightly messy raw text, then do not (put multiple newlines after the [/quote])

[quote]quoted text[/quote]

your text

• Instead do (put only a single newline after the [/quote])

[quote]quoted text[/quote]
your text

• Make sure you provide proper citations for every non-trivial claim you make.
• Don't overuse formatting but don't be afraid to use it either.
• Never use [center][/center]. It might look good on your screen, but once the window gets bigger it will become really ugly.
• Don't embed huge images (in either resolution or filesize). If the resolution can't be reduced, rescale it with something like [img=300x400][/img]. For extra convenience put [url=url to image][/url] around everything. (Example)
• [Ad] Don't get caught using one of these arguing techniques.

After writing

• If you notice a mistake, edit your reply and use the overstrike effect to indicate the change.
• Do not edit your reply to include an answer to a later reply. It will screw up the chronology.
• If you want to add content to your reply immediately after writing it, edit it instead of making a double post. However, if you want to add content to the topic itself and your last post was a while ago, then do double post (since edits don't notify people watching the topic).
