Here is some info which I hope may be of some help.

A tag generator: http://egmstrategy.com/ice/tag-generator.cfm for Technorati, Flickr, Del.icio.us and Furl. Also creates social bookmarks for the previous plus Digg, Yahoo, Blinklist, Spurl, Reddit and Furl

Two different tools to mass submit and create tags available at downloads.com
delicious submit
delicioso

These tools are meant for mass submitting urls and tags to Del.icio.us

The problem with this is Del.icio.us has noarchive, nofollow, noindex

However you can import these urls and tags into a Jots account

Jots does not have noarchive, nofollow, noindex

Multiple Jots accounts can be created and you can import the urls and tags to all of them. Theoretically this can give you numerous PR5 links in a few minutes.

This will probably lead to lots of spam, which will probably lead Jots to change to noarchive, nofollow, noindex, as Graeme mentioned.

Many of these sites have toolbar plugins. I personally don’t want toolbar plugins, but I have more than one OS installation on the same computer, so I may install the plugins into the OS I rarely use.

I am using Windows 2000. I have server and professional on the same computer, but you could have two copies of professional. I believe you can do the same with XP if you partition the hard drive. It can be very useful when your OS crashes to still be able to access if from the other OS.

Yahoo also has a toolbar that allows you to bookmark and add tags, but I believe you need the toolbar to add the tags. Not sure of this at this moment as I have previously bookmarked lots of sites with yahoo without installing the toolbar, although I never tagged.
