Change "Blogs" to "Sites" and hide "Private" sites.


Is there a way to do the following:

1. Change the Blogs Directory to use /sites/ instead of /blogs/ in the URL? In addition, is there a way to have the listing use "Sites" instead of "Blogs"? Since WordPress is going more to the Sites model, this would be helpful. Our latest WordPress multi-site install is focused more on Sites and is being used by Faculty who would prefer the term "Sites".

2. Is there a way to hide Sites that are listed as Private? In other words, the sites that have the Privacy option set to "Block Search Engines". We are currently using a more rudimentary list for sites, but it does offer this feature. When we create new sites, we prefer to hide them until they are ready to be shared more widely.
