Will need to be knowledgable in messenger manipulation. Skype, in particular.
Email me for further details.

Skills: Java, decent english.

At least a few times , I have seen discussions on messenger / live chat  suddenly end,  it seems they can be easily manipulated.  At first I thought it was a problem with the chat operator, but now I know better.  There is no replacement for talking on phone.
