I got a mail from someone claiming to be from the legal department of IBM.co.uk, asking if I had legal permission to use their logo on my site. A quite surprising question, if you ask me, since I have a legal disclaimer at the bottom of this page. But since I had not that kind of legal permission, and it is IBM's logo after all (my motto in those matters is : never meddle with companies whose legal department is at least as large as their IT division), so I removed the logo in question, and replaced it with a homemade one.
