We offer a "free for all" roommate finder via our roommate forum. You can start your own free roommate search, you can look at roommate wanted ads, find rooms for rent, all for free, but your roommate ad will only be as appealing and effective as YOU make it.
To successfully find a roommate here will require a bit of thought, a small amount of actual typing, and the ability to read and follow simple instructions.
However, if you can manage to do that, your roommate search will be pretty easy. You can also get roommate inquiries or other roommate ads sent to you automatically, either by email or RSS feed.
For those looking for a more directed roommate search with a in-depth questionnaire covering many relevant questions to ask when looking for a roommate, we also recommend:
