Replied in that for sale thread yesterday, checked it a couple times for replies, just clicked on “my posts” and saw there was a reply but when trying to open the topic it’s gone all of sudden.
Did it get deleted by accident or are the alloys sold ?
Normally For Sale posts only get deleted if they are running old or the seller has asked for it to be removed ie put Sold in the thread or title.
If it was still in your “Find all posts by Medic-one” but not there when you click on it then you might find that your cache hadn’t been updated 
The thread is now in the deleted section and are now sold.

Damn, should have replied to that thread earlier then.
Cheers Rich for the update.
