Thank you! I'm glad I asked.
I only looked at 2 pages of the discussion you linked to Jenny but it seems those were about mobile numbers which I don't use. I am not sure really how/where to sign into my account. I looked under profile last night thinking that was where to go. I guess you mean go to www.steampowered.com
or whatever it is? I never have a reason to go there.
Thank you mj2c for your input and confirming it is legit.
And thanks Draclvr. I know I had just been reading on a different board the other day about this stuff.
I will hold off for now.
