Assinging projects or articles plugin.. EasyBlog

Hello guys.

I would like to know if there is some software or script, plugin or extension i can use to assign projects to bloggers..

For example i need to create som article about Smartphones, so i send the request to a group of bloggers i previously created on my easyblog backend, and then ALL the bloggers receive this request and some of them take the petition?

Is something like that available..?

Hope you can suggestrme something that works in a simmilar way.

Thanks.

Best Regards!
