Change cryptic error message for wrong homepage URL to something easier to understand

Hi there,

we recently run a Drupal 6 website under an usability testing session. One of the tasks users were needed to accomplish were adding a comment to a node. The full commenter details fields (name, mail, website, etc.) were enable so user could insert a website address. Most of them failed to insert a valid fully qualified URL and instead used something like www.example.com.

Then on comment submission this message would be returned:
The URL of your homepage is not valid. Remember that it must be fully qualified, i.e. of the form <code>http://example.com/directory</code>.

From a strictly technical point of view this message is pretty perfect. Unfortunately none of the tested user were able to understand what an URL actually is and what fully qualified means. I should say that this message pretty confused our users.

I would suggest using a more easier and less technical language like:
The address of your homepage is not valid. Remember that it must be in the form <code>http://example.com/directory</code>.

Hope this helps,
