Definitely, I'm mainly replying to this thread so it goes into "my replies" and I can find the link easily.
That particular panel should be included in the normal account profile. I've gone to that area several times trying to find where I could change my email and password.
I'm also a little wary of changing it because I don't want to create any problems with activations, but the email I have on file is no good and I actually would like to get the Stardock newsletter.
