wikiHow is a site for readers of all ages and for contributors over 13. Thus, the conversation level is expected to be mature and respectful.
Avoid asking "Do you want to be friends?". Asking someone if they want to be friends isn't an effective way to make friends on wikiHow. Most of all, do not keep pestering people with this question. Avoid asking personal questions such as how old someone is, where they live or what grade level they are at in school. This can get you some warnings. Respect people's privacy. Absolutely never ask what school/college/workplace they go to. This gives away a lot of information about a person, and many people don't wish to reveal this much information online. Since this isn't a social networking site, do not expect people to divulge more than they feel is appropriate to collaborate together.
