Sorry about this, but using latest Firefox can't get a link to show.
Tried latest Internet Explorer, but it won't even open a 'new discussion' form.
I would do this on my existing test post, but you can't edit them.
Following instructions as per: highlight the following url and then put the url into the url box:
http://new.britishcycling.org.uk/bikechat/new
Its showing properly in the form, so lets see what happens in the actual post.
