Justforeveryone.com is different for 2 main reasons:
Most other website charge you to place an ad for 1-2 weeks and then charge for additional items eg featured listing, photo uploads.etc. So if you ad does not sell within the time frame you have to place another. Justforeveryone.com charges you for how long you wish to place an ad. All packages come with photo upload and google mapping as standard.
The second feature about Jusrforeveyone.com, is that although the general public can view ads on this site, users must register in order to contact the owner of the ad. This should reduce the amount of fake or fradulent inquiries.
Although you may enter your details, none of that information can be viewed by the public. There is custom fields where you may add your email, address or phone if you wish for these details to be viewed by other user(s)
