Just some more questions: I am glad you and the other guy finally came up with this:
1. Categories: Does this work where it will use the category, no matter the placement, in another blog? For example, I post to the master post under the parent category "cats", but other blogs use the category as a child under "pets".
Does this still get placed in the "cats" section, or will another post be created? Currently I am organizing all the blogs the same, but wanted to know the effects.
2. Images/Attachments: Does this re-duplicate images and attachments. Or does it keeps the same location as in the editor?
3. Duplicate: Is it possible to modify the code where sub-blogs automatically get a canonical tag/ or a no follow tag?
4. Does this stress out the server if there were to be a post to over 50+ blogs? It won't be used much, but wondering if there would be a lot of queries done while its being used.
Hey thanks a lot for this plugin. Really appreciate the work, and will donate toward its cause soon.
