When sending out a link request letter, is it better to use a question mark or period at the end of the sentence in which you ask request the link?
Example: I wanted to request if you could please include a link to my site from the links page of your site
At the end of the above example, would you use a question mark or period. I have read that a question mark is ok and I have also read that when making a request, you should use a period.
