Peter Luschny: Robert, this link comes from a time where you (if you did not want to publish your email address) could instead specify a link to your website. As far as I know this is no longer possible. This has nothing to do with the sequence.

Jon E. Schoenfield: If Hobson were a registered user (I'm guessing he's not ... I didn't see a "Nick Hobson" or a "Nicholas Hobson" in the list of Registered Users), I'd say it should be deleted. However, if he's not a registered user ... maybe the URL should remain in the sequence, in case users want to contact him?  I don't know.   ?:-|

Robert Israel: Should Hobson's home page be listed as a link here?  If this sequence is referenced in  one of the puzzles, it's not obvious.
