Code Available via the files form at the bottom of this page original source: in the Nucleus Forum at http://forum.nucleuscms.org/viewtopic.php?p=28951#28951 (Author: TrenT)
This plugin was developed by Andrew Black to have new blogs created for each member when they register where they are the blog admin and able to post. Gives the ability to have a 'blogger' type service.
This plugin works with the standard account creation file that ships with Nucleus at http://www.yoursite.com/createaccount.html and will create the blog for the user after they have signed up using this process. It will also work if you are using the NP_phpBB plugin as well.
Copy and paste the code from the nucleus forum at http://forum.nucleuscms.org/viewtopic.php?p=28951#28951 into a file called NP_NewMemberBlog.php. Upload the file into the nucleus plugin directory, than install or update the subscription list. :)
