Hi Chris
Please accept my apologies for not sorting out this problem earlier today, I've been busy on domestic duties so I missed looking in this afternoon as I normally would.
Links are allowed but the problem is that Haymarket have installed some very effective anti-spam software to stop the 50+ spammers that the forum was attracting every day.
Every now and again a link from a genuine forum member is detected and diverted to a moderator edit away from the forum page. I normally check the edit suite 3 or 4 times every day and take the appropriate action for the post containing the link to appear.
Because of time pressure I've only just checked the edit and your post with the link has now appeared on the forum.
The box with the letters is an affirmation box which lessens the chances of remotely generated spam getting through, if you continue to have to fill in this box when adding forum posts please email me via the 'contact a moderator' link and I'll get the issue rectified for you.
