Here's how to get really great control over cross-linking tons of sites using Scrubz.

You can use the free version of Scrubz to do this:
www.tuelz.com/download.html

Also, this thread assumes you have a working understanding of Scrubz...You need help actually using Scrubz, please post on the Scrubz support thread here:

In the Newz Tuel, create a category called:
YourTopic-tin

Save.

Now, every time you create new blogs/resources, add the URL to its RSS pheed in this category of The Newz Tuel.

Next, open Scrubz and create a project for this new cateogory.

It may take a few minutes to gather all the pheeds, but from here you will be able to add/delete any RSS pheeds from your network.

It's also easy to combine and manage multiple pheeds this way.

WARNING: I doubt NewzTuel can handle 1000 RSS pheeds, without a lot of planning and spreading out the "check" times. Even then, if there was a glitch, everything could really back up.

Use Scrubz on your newest pheeds/blogs, deleting older files over time or as needed.
