I've got a better idea - the OP comes back when they've *earned* enough merits to be able to display images. Hopefully they will have also learned a little of the nuances of the Forum
That is a better one but my suggestion is only just for the publicity of the images or the whole site in a faster way, so I introduced him the copper membership status, if only he do feel like it.
why the referal code was a bad idea.
Because it's stated on the number 4 of Forum rules, his signature space or profile text space should do just fine if he puts it in there.
