It costs a few bucks but you can do that with gravity forms and a plugin or two for it. The form bit is easy. The trick is registering folks into wp. hope that helps, Nigel
i want to increase the visitors, doing SEO but need more traffic which can help me boost adsense revenue also
For boost traffic you need good content and regular updates of your website or blog. If you need olx type post you can use paid classified theme Thanks
