I installed a context menu feature for ms internet explorer here at antville.org similar to the one of blogger.com.

Installation is pretty simple (imho):

1. Point your browser to http://alias.antville.org/menuext.reg (be sure to replace alias with your weblog's alias)
2. If you trust me, simply choose "Open file from its current location" (or whatever it says in english for "Die Datei von ihrem aktuellen Ort öffnen") – if you belong to the noble group of internet sceptics you rather should download the file, examine it in your favorite editor and then decide to install it.
3. After installation (ie. writing a few lines in the registry) you should open a new instance of internet explorer and then find a new entry in the context menu called "Post to sitename" with sitename certainly being your weblog's title.

To use the context menu simply go to any website, select some text and click on the new entry. In effect, your weblog's story editor should open with the editor field containing the website's URL and the selected text ready for editing and posting.

Btw. if anyone wants to contribute a similar functionality for other browsers just let me know how the principle works and maybe we can find a way to implement this in antville, too.
