Given the nature of the site - Quality Questions and Answers - just simply up-voting for the sake of up-voting is typically discouraged. Not that anyone of your questions/answers isn't good, but it should be up-voted based on merit/quality - not by request.

You're at a rep of 33 now, you're 17 points away from being able to comment again. I'm sure you can find a few [Unanswered Questions](http://ubuntu.stackexchange.com/unanswered) which could use some attention - or possibly [Ask a Question](http://ubuntu.stackexchange.com/questions/ask) yourself!
