Constant Content

I have some articles that I have written for a hobbist magazine that I could sell here, but since the hobby is pretty specific I suspect that the buyer would want Unique rights.

Am I correct in thinking that I can only sell this as Usage? Is there some way I can put in my summary that I would remove the article from the site after sale even though it is not listed as Unique or Full rights?

does any of this make sense?

If it has been published any where else you can not ask Unique or Full Rights prices for. You can rewrite the articles so they are different and sell these, but be careful you don't plagiarize your own article (if that's possible).

A customer buying a unique article expects to be the only one that owns rights to this article.

Thanks...
