If I understand the OP correctly, he is trying to solve the problem of e-mail clients using other prefixes instead of "Re:" for replies (for example "AW:" or "Odp:" - these are among a few I encountered myself). When you exchange emails back and forth, this usually leads to chain of prefixes like "Re: Odp: Re: Odp: ..." at the beginning of the subject line. He is trying to replace all these strings by a proper "Re:". -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
