Yet I have just come across a website with the following sentence:

we have combined many years of copyrighting skills to create magical letters for every occasion.

As much as the misuse of copyrighting annoys me, it being misused in a sentence where the writer claims to be an expert writer  is shocking. Of course, I am also curious as how to someone combines years to create anything.

Before I get on my soap box about people posing as experts and (in my opinion) trying to fool people*, let me give you a much better version of the above sentence:

Together, we have many years of copywriting experience which we use to create magical letters for every occasion.

* I don’t know anything else about the writing skills of the site using the above sentence so I am not commenting on their level of expertise or claiming they are unethical. It is just a general comment that I hate people presenting themselves as more than they are and errors such as this are sometimes an indicator of such behaviour.
