I want to thank all of you for your responses. The viral information should have been obvious to me. But being new to the WoW scene - counting the addons - well... I really felt as if I was in uncharted waters.
Never-the-less, all of your responses are great. Including "Seerah's" response about hotmail. Not to mention you guys (girls) being addon users yourself and saying which sites you trust... well; that's also comforting to know.
I will stick with your recommendations.
Now I search for the WowAceUpdater to help me out some more. Here's hoping the learning curve is small
!
Thank you again.
Ps: "Layrajha" - Thanks for the info on the .jpg compression. That was news to me.
