When information must be entered -- such as a text message or a login name -- the BBS prompts for it by presenting the name of the field to be filled, followed by a colon ("Password:" or "Message:", for example).
There are two types of fields: one line and multiple lines. If the field is one line in size, the BBS lets you type it on the same line as the field name. You then type the field, followed by a return. If the field is multiple lines in size, the BBS puts a carriage return after the colon (starting you on a new line). You then type as many lines as you want, followed by a period (.) on a line by itself.
If auto-wrap is enabled (the default), lines longer than 75 characters are automatically split up.
