Thanks for the help CvP
Yes, you do seem to have it nailed on your site, but unfortunately, after updating to 4.1.1, any time I add a new user profile, for some reason it was adding them to the main profile page under location and the other stock fields.
I have now found a really nice alternative, it goes in the bottom of the postbit and then the specs are shown in the sig area, looks great and very neat. Not sure it would be right to post it here, but if you want to PM me, I can send the link for it on here.
