Since you are here, you very well know the importance of a backlink. More backlinks from quality sites may give your site the page rank it requires to boost traffic.
Here is a list
of some dofollow forums which I refer to get my set of backlinks. These have a good Google page rank. You need to register on them to post or to comment. Once you are through, just try and search topics related to your site/blog and start interacting by posting new topics, comments, replies to post etc. Do not forget to leave a personalized signature with a link to your site/blog and make sure that you stay active as much as possible. Since these forums are very active, you may get your results earlier than expected. Every effort counts :)
