So I posted to 'General' and got a messge that the post has been moved to another forum but it doesn't say which one. It looks as if it has attempted to move it to a forum to which I have no access and failed. Not helpful.
Your "for sale" post has gone into the MarketPlace section of the forum, which is only available to registered members of the site. It is only a small fee to get access (I believe £5).
If you click on the "Merchandise" section above you can pay this by Paypal.
There is a nominal fee for market place access Nigel...I think it's still in place. When you joined you may have missed this but it's still availabe to you as an "upgrade" for around £2.
Thanks for your help. I still have no idea how to find the marketplace or my post. Can you tell me where to look? It is not listed under 'Forums'. Or must I wait for some time before I have access? I think others can see my post as I have had a reply but I can't.
