[TheForge] Fwd: Anvil repair

[Dave Mudge]

Your tech information is good and I am sure that it is well appreciated.
However, the robot will not accept attachments, html code, colors, pictures
or anything cool. It only likes plain text. I wish that it (the robot)
wasn't so old school, but what do you want for nothing?,,, something free?

love and peace,
your list mom,
dave m
