How can I create a multi author blog in wordpress? By doing so who will have the rights of posts made by other authors?
In order to do this, you'll need to be able to install plug-ins on your WordPress account. If you are using a free WordPress account this won't be possible. Furthermore, if you are hosting your site or blog on WordPress, you'll need to purchase the top hosting package in order to install the plug-ins for your site. Otherwise, you'll need to host your WordPress account with a different hosting company.
