How to report an extension bug

Hi! I was playing with contentslider extension, and i found a bug. Because the module doesnt have a specific topic i report my problem in these general forum. But i will like to report this bug to the creator of the extension. In the extension list there is only the website of stefan. I think it would be great if the creators of the extension public a email, for be in touch more directly. am i missing some information of the extension authors in some section?

what do you think?
cheers.
