(Really) Bad Uses for e-mail

(don't try these; please!)

• Sending your 128-channel 1024 x 1024 spectral line cube to your colleague (even if it is a breakthrough)

• Distributing plain text files in an overhead-heavy binary format, e.g. badly prepared PDF files

• Sending medium-size or large files to a large mailing list (>100 members)

• Star Wars MPEG trailers (just say no)
