Review the rules and etiquette before posting in a group

Individual online communities have different expectations for how their participants should behave. When you join an online group, such as a Facebook group or a discussion forum, take a few moments to read the rules of the group first. You can also get a sense of how you’re expected to behave by observing the way established group members interact.
In most groups, members are expected to be respectful and courteous to each other.
There may also be rules about what kinds of content you are allowed to post. For example, some groups forbid content that is “not safe for work” (snake game), meaning you shouldn’t post anything that someone wouldn’t want to get caught looking at on a work computer.
