Hi, it seems as the download links for themes are some redirect or javascript link, but looks like a zip file.
Nothing wrong with that, except when you want to download a the by using wget (on the webserver) and copying the link; you don't get the zip, but some html file.
Since most people do not download the file to their home pc, but use it on their webserver, i can't see why this could be useful...
Also, some Themes have limited capabilities, it would be useful if the options were noted in the text. Like if there is a search-page and such.
