Thanks!
-When i change the album artwork image to ItunesArtwork\artwork.jpg, it works fine for a while, but then the whole tile just disappears again (does it require itunes to be open? if so, can I change that?)
-With email, I've just set up a gmail account and forwarded my live mail emails to it, so they can be displayed in this skin. It works well now! Maybe you could include a little popup window which can display the email contents without opening a browser?
-I've edited the recycle bin ini as you suggested, but now rainmeter crashes whenever i click the button?
There is one other problem, which is hard to describe. I'm using Rainmeter 1.2 Beta. I have all of the panels and the background of the skins set to 'on desktop', so that when i click the show desktop button in Windows 7 i can see the skin. Unfortunately this causes some issues. Its like the translucent 'background' keeps jumping in front of the panels, so i have to constantly right click, select position, and the 'on desktop' for the background over and over again so that i can use the panels. Is there a way i can stop this? Its becoming annoying 
I love the skin!
-installed on both of my computers 
Thanks!
- The tile disappears because it can't find artwork.jpg, possibly because some of your albumart is in PNG format, so the file is artwork.png instead of jpg. If you have more albumart in png format, use iTunesArtwork\artwork.png. Or a really elegant solution would be to also add the placeholder image for albumart (albumart.png) under the last used albumart (artwork.jpg/png), like this:
[MeterAlbum]
Meter=IMAGE
ImageName=albumart.png
X=0
Y=0
W=150
H=150
[MeterAlbum2]
Meter=IMAGE
ImageName=iTunesArtwork\artwork.jpg
X=0
Y=0
W=150
H=150
[MeasureAlbumArt]
Measure=Plugin
Plugin=Plugins\iTunesPlugin.dll
Command=GetCurrentTrackArtwork
DefaultArtwork=img\defaultartwork.png
This way the note image is the most bottom image, and is only visible, when there isn't any artwork available and it can't get last used albumart (albumart is in different file format/file doesn't exist). If artwork.jpg/png is found, it will show that on top of the placeholder and current albumart will go on top of that. So basicly, it would be: Placeholder -> Last used albumart -> Current albumart. You could also include another meter for the other file format, so that if it doesn't find current albumart and artwork.jpg, it tries artwork.png (or the other way around):
[MeterAlbum]
Meter=IMAGE
ImageName=albumart.png
X=0
Y=0
W=150
H=150
[MeterAlbum2]
Meter=IMAGE
ImageName=iTunesArtwork\artwork.png
X=0
Y=0
W=150
H=150
[MeterAlbum3]
Meter=IMAGE
ImageName=iTunesArtwork\artwork.jpg
X=0
Y=0
W=150
H=150
[MeasureAlbumArt]
Measure=Plugin
Plugin=Plugins\iTunesPlugin.dll
Command=GetCurrentTrackArtwork
DefaultArtwork=img\defaultartwork.png
- It's not possible to parse e-mail contents from the RSS so sorry, no.
- It seems that the plugin bang EmptyBin doesn't work with Windows 7 (I think), but just tried and EmptyBinSilent should work, so change it to this:
ButtonCommand=!RainmeterPluginBang "MeasureBin EmptyBinSilent"
And to your last problem, I don't know exactly how to solve that but we're looking into it.
