Welcome, Elquemataranas
This is an open forum, and you are welcome to as much participation as you can stand.
In fact, as SDG explained (thanks, Steve!), this forum is so open as to not have a login. There's no way yet to cast an identity in electronic stone, so we have to rely on collective memory to keep track of who's who. Non-duplicating handles is the only way...
... which is precisely what I would have said in an email, besides "welcome".
