Messages sent by WebGate are sent with more information than just the message itself. Messages will be prefixed with the reliapage index (if enabled), the block number (if it is part of a large message that has been broken into smaller pieces. i.e. 1 of 3, 2 of 3, 3 of 3), the sender's name (can be optionally disabled), the subject of the message (optional), and then the message itself. Each of these fields is separated with a colon (:). Most pagers have a limited character set usually consisting of upper and lower case letters, numbers, and some symbols (periods, commas, dollar signs, exclamation points, etc.). Non-printing characters such as carriage returns, line feeds, and tabs can optionally be removed from a recipient's messages.
