*************************************Tripcodes and capcodes
Main article: Tripcode
In a tripcode system, a secret password is added to the user's name following a separator character (often an octothorpe). This password, or tripcode, is hashed into a special key, or trip, distinguishable from the name by HTML styles. Tripcodes cannot be faked but on some types of forum software they are insecure and can be guessed.
Moderators and administrators will frequently assign themselves capcodes, or tripcodes where the guessable trip is replaced with a special notice (such as "# Administrator"), or cap.
Main article: Personal message
A private message is a message sent in private from a member to one or more other members. The ability to send so-called carbon copies is sometimes available. When sending a carbon copy (cc), the users to whom the message is sent directly will not be aware of the recipients of the carbon copy or even if one was sent in the first place.[example 1]
Private messages are generally used for personal conversations. They can also be used with tripcodes-- a message is addressed to a public trip and can be picked up by typing in the tripcode.
Hit-and-run posting refers to a tactic where a poster at an internet forum enters, makes a post, only to disappear immediately after. The term comes from the hit-and-run crime on auto vehicles, in which the driver hits another car causing an accident and runs away. It is also known as making a "drive-by" posting, a play on the phrase drive-by shooting. The post often consists of a lengthy text making lots of claims that can be, but are not always, on topic.
Another variety is the sole posting of a URL or link that leads to material that might be used as a discussion primer, but with no added opinion of the poster. It differs from plain spam since forum spam often is posted by spambots, while hit-and-run posting on the other hand is done by a real person. Also, while spam mostly consists of advertising, hit-and-run posts usually have at least some bearing on the topic at hand. However, since the poster doesn't stay around to defend the posted material, or even discuss it, it is considered disrespectful, especially by forum regulars who tend to be angered by the fact that the hit-and-run doesn't become obvious until some or several replies already have been made.
Hit-and-run posting often follow the principle of "throw enough in and some will stick", where the poster hopes that even though he/she will not defend the post, it might at least persuade someone of its merits, and sometimes its motive is plain flamebaiting. Answering hit-and-run postings after they have been diagnosed as such is sometimes considered "feeding the trolls" and is therefore discouraged. Hit-and-run posting tends to occur more frequent in debate on controversial topics.
The term "hit-and-run posting" is sometimes used, unjustifiably, against people who don't have as much time to spend on a forum as others and therefore have trouble keeping up with the posting pace.
