If you're adding me, do comment, or chances are your add will go unnoticed due to the amount of green envelopes I get and the fact that I can't be arsed to look at them unless my interest has been tickled somehow. And I just noticed the green envelope is now a green bell, and it probably has been for years, so that illustrates how much I can't be arsed.
For the rest, have at it, I'm usually friendly, until I'm not.
