I found what I needed. It is called “post type”. A plugin that I could find was Types – Custom Fields and Custom Post Types Management. Let me know if you have suggestions for another good one well maintained.
Thanks
I had 2000 blogs and 90% of them were spams. Deleting them one by one was tedious. One way I have done that is by editing wpmu-blogs.php to allow me to delete 100 blog at once. I change the variable for 15 blogs per page to 100:
$num = isset( $_GET[‘num’] ) ? intval( $_GET[‘num’] ) : 100;
Then I checked all of them for deletion per default with the following change
this
<input type=’checkbox’ id=’blog_<?php echo $blog[‘blog_id’] ?>’ name=’allblogs[]’ value='<?php echo $blog[‘blog_id’] ?>’ />
to
<input type=’checkbox’ id=’blog_<?php echo $blog[‘blog_id’] ?>’ name=’allblogs[]’ value='<?php echo $blog[‘blog_id’] ?>’ checked=”checked” />
If you sort by last update date then you can delete the oldest one.
