You should post/move this topic in the Project Development discussion as you are looking for other participants/members in your website. Also by moving the topic you must discuss the website itself on what are you planning to post or what you are planning to do in order for you to catch the attention of some people. 1000 people is a lot to ask for and I wonder how each and everyone of you will communicate to each other and personally I don't think you can handle it on your own so maybe try to start on a small team first.
