Steam question

[abcxyz]

Well I couldn't find anywhere else to post this thread, anywhere better at least, so it'll be here.

My question is, around what time did steam start using usernames instead of long email log ins?

I know for a fact that most 2005 have usernames, but other than that I have no clue.

Thanks again!

2007 was it not?
