I agree that there should be a theme for people without DDI subscriptions, and I guess it would be nice if there were a choice of themes for them as well. However, I don't think that official themes and custom themes should be in the same proposal, because it is really going to slow things down.
It doesn't make sense to have official themes be delayed while we attempt to create and balance a number of custom themes. Should all themes ever be held up because I think the level 1 power on CaBaNa's Ex-Guard theme is a little too good, or because there's disagreement whether Know How To Stay Out Of Trouble should give a bonus to initiative or perception? No. That's a little silly. What we should do is approve (or disapprove) themes in general now, and then look at more custom themes as people submit them.
So
yes to Luinnar's proposal
here, which allows non-DS themes and twilsemail's Adventurer theme.
