Why davrob60? "dav" is for David, "rob" is for Robitaille, 60 is meaningless.
In fact, it comes for somewhere around 1996 when I open a hotmail account. While hotmail was still new on the web, davrob was already used. So I choose 60 because I didn't like davrob2. I think 60 were the last two digits of my mouse's serial number. Anyway, I stick with this ID and it's my login every here and there on the net. I don't use that hotmail account anymore, it has been deleted somehow when Microsoft put some stupid activity rules that are now gone. I got a Gmail using the same id. That's how you could join me.
If I make funny phrase, it's because English is only my 3th language. The first one is french and the second one is a version of Basic that is old enough to have a line number in front of each statement.
