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.
