A friendly suggestion: if you are interested to work with (recruit or apply to) someone you are already connected to but hesitate to ask for whatever reason it may be, Jobrupt (<a href="http://www.jobrupt.com" >) may help you to make the first step towards her/him. It's a free small utility inspired by some form of matchmaking and it has proven useful for some small circle. I hope it helps some more people, so give it a try.
