@ bahamamark regarding themes
A good point here, however, gotta say few things
First of all, majority of Vivvo themes, including the new one, are made to be supported by all major browsers, hell, if you look at new 4.5 theme, it still looks decent even in IE6
Second, the themes from rockettheme.com, oh well, I guess they look ok, however, let's just make quick compare between Vivvo and rocket themes.
If you look at new 4.5 theme, and even 4.1 theme, in firebug, fully loaded, home page weights approximately 280kb, while at rocket themes, due to use of big graphic images, both for boxes and backgrounds, I couldn't find any under 500kb (I simply looked ad 10 random themes).
Now, take this in consideration - Vivvo users + their servers (some good, some ok, some pretty bad), imagine how bad would theme that weight let's say 700kb (but looks bitchin') load.
I'm not saying that Vivvo themes are state of the art design, they are far from that, but for the price, well, IMO, they are decent
