I've been getting spoofed emails from only 2 forums, this one and another http://www.khouse.org which look exactly alike. I believe they are the same programs. The coincidence leads me to think someone perhaps has discovered a way to hack in to the program and send members emails.
I just wanted to warn you not to click on anything that doesn't look like the usual knittinghelp.com emails.
A simple way to keep this from happening might be for IT to change some file names, as a hacker is looking in default file names. Just a thought.
