Future techtorials

By Sean McGrath Add a new comment

May 19, 2009, 4:01 PM — I'm soliciting feedback/suggestions on the techtorials I have been doing with ITworld.

I know that the handwriting quality is a problem for some people. It's tough writing with a pen interface and my handwriting is bad to start with...I have some ideas to address that.

If you have something to say on the topic please use the Left Field Techtorials feedback site or comment on this blog, or e-mail me.
