My daughter Diana spent two years working in Silicon Valley before starting business school and has been very helpful with information technology issues I have faced.  For the cognoscenti, as further warrant of her tech-cred, it is also worth noting that Diana was co-founder of ROFLCon and has been on the program of major tech conferences. 

So by the wonders of reblogging, I am going to conscript her as the occasional IT columnist for this blog when I think one of her posts would be useful to readers. This post seemed useful since coauthors collaborating by Skype (as I do frequently with my coauthors) might find it valuable to record their Skype conversations.
