For me, this page is 3-4 screens long, and has too much of the wrong stuff in it. I would like to use it as my Home Page when I open my browser.

Therefore I would like it to be a single screen of information with no actual lists (only jump-to links) for Recent Messages, Completed Games, Available Tournaments, and Bookmarked Games. Two of these already have these links in the My Summary section.

NOTE: I have observed that I can hide each of the lists and I do, but the next time I open my browser they have all been opened again.

I would like to be able to open my browser and have MyHome come up to display in its shorter form. Is this possible? or would it be possible with Firefox?

I agree.

Once you hide a list I think it should remain hidden the next time you log on.
