Yes, the discussion forum does behave differently to the BTL comments section. If you paste a plain text URL here, it tries to insert a snapshot of the page; but it only displays on certain browsers, depending on their privacy preferences.
I notified Craig about the issue you raised via email last night. As the text is quite ambiguous, it would be folly to modify it without consulting him. But he rarely responds to prompts. He should now be aware of the issue, but if he doesn’t feel it’s important enough to amend (or to ask moderators to amend on his behalf), then it will just remain as written (sic).
Thanks for your eagle eyes. If you see anything else amiss, let us know in this forum.
