I need some good suggestions to get more visitors & new members to my forums (http://www.webdevshack.com/forum/). I will be advertising it on similar websites soon. I started a untargeted campaign with targetvisitors.info, but that hasn't helped too much yet..

What else can I do? Run contests? I was thinking of running a contest to give a free domain name + 6months/1 year of hosting to a lucky member.

Help me :(

Well best bet is to upload content, thats the only way people will get chatting. I used to run a forums thats had over 8000 members and that took me 2 years to make and design that forums, dont give up as people will talk if you have content that people want. If you spend hours and hours then you might have a chance.
