AddTags is a piece of software for RISC OS computers, designed to add random taglines to outgoing email and news (usenet) posts. The software takes a rule-based approach, so where and when taglines are added is fully controlled.
Tags are not limited to a single line - within AddTags they are still kept on one line, but if certain control sequences are found within a tag, line breaks will be inserted when the tag is added to the outgoing post.
