itrader has been deleted and I'll be editing it out of the postbit very soon
It sometimes says about the priveledges because the site is set up so until you have made a post it won't allow you to look at or download attachments - usually once the first post has been made, it takes about fifteen minutes for the site to update and you should be okay from there on in. Try hard refreshing, if it doesn't work let me know and I'll sort out your settings for you manually
