RSC helps you change your mail signature. All you have to do is set up one or several signature database files containing the text you want to use as your signatures, and RSC sets them for you automatically.

You can either choose which signature you want to set manually, or you can (as the name suggests) let it randomly find one from the databases.

It can also set the song currently playing in Winamp as your signature.

Additionally you can let it change your signature every x minutes.

This program should work with most email clients, as long as the client supports reading signatures from an external text file.
