Iam not sure if it is just me , or if it the web site , but i am fairly sure that searches for :
themes
profiles
downloads

Do not work as they should be , i would like to know if the fault is at my end or infact if it is the website itself

Well...there is no search for themes and profile and download searches work fine for me.

same thing here. the problem's on your end tactolark.

it will be nice to add a search fucntion for the theme...
when you would like to search for a specifique theme, it's the hell to find it ....

I believe it's already been requested, and put on the "To Do" list. which is REALLY long, or so I've heard. So in other words apple, just sit tight, it'll be here before you know it. or at least before 2010. :P
