- Signatures must link to the user's userpage or the user's talk page if he or she prefers not to have a user page on this wiki. Signatures may link to both if the user so desires. The name does not need to be the user's exact account name, but it must be a name by which the user is widely known. Without this provision, signatures do not provide the useful ability to identify a comment from a certain user on a page.
- Signatures cannot contain more than two images, since signatures with more than this can cause computers to load them slowly.
- Images contained in signatures may not be higher than 60 pixels. Users can scale images to 31px high without distorting them by using the code: [[File:Example.png|0x60px]]
- Signatures must not contain linebreaks. This results in a line break when the signature is used, which interferes with formatting and other page code.
- Signatures that use HTML tags must be balanced. This means that every <span> must have a matching </span>. You can tell if your signature is balanced by typing something after it. If it is plain text, then your signature is balanced.
- Signatures must not be excessively long. There is no set limit for how long is too long, but use common sense. In general it would be preferred if, when the signature is standing alone with no other text before it, it doesn't exceed two lines.
- Please remember to always sign talk pages and forum discussions, claims, votes, etc.
