sorts are often automatically appended. These are typically couched in legal jargon, but it is unclear what weight they have in law, and they are routinely lampooned. Business emails may also use some signature block elements mandated by local laws: Germany requires companies to disclose their company name, registration number, place of registration etc. in email signatures, in any business-related emails. Ireland's Director of Corporate Enforcement requires all limited companies operating websites to disclose such information in their emails. The UK's ECommerce Regulations (reflecting EU law) require this information in all emails from limited companies. In England and Wales the case of Mehta v J Pereira Fernandes clarified that an email address header added to an email by the email application did not count as a signature for legal purposes, but While criticized by some as overly bureaucratic, these regulations only extend existing laws for paper business correspondence to email. Standard delimiter The Usenet news system standards say that a signature block is conventionally delimited from the body of the message by a single line consisting of exactly two hyphens, followed by a space, followed by the end of line (i.e., in C-notation: "-- \n"). This latter prescription, which goes by many names, including "sig dashes", "signature cut line", "sig-marker", "sig separator" and "signature delimiter", allows software to automatically mark or remove the sig block as the receiver desires. Most Usenet clients (including, for example, Mozilla Thunderbird) will recognize the “dash dash space” delimiter in a news article and will cut off the signature below it when inserting a quote of the original message into the composition window for a reply. Although the Usenet standards strictly apply only to Usenet news articles, this same delimiter convention is widely used in email messages as well, and email clients (such as K-9 and Opera Mail) commonly use it for recognition and special handling of signatures in email. Internet forums On web forums, the rules are often less strict on how a signature block is formatted, as Web browsers typically are not operated within the same constraints as text interface applications. Users will typically define their signature as part of their profile. Depending on the board's capabilities, signatures may range from a simple line or two of text to an elaborately constructed HTML piece. Images are often allowed as well, including dynamically updated images usually hosted remotely and modified by a server-side script.
