[Greasemonkey] Any method to transfer infromation between two pages

[Vikas Pandey]

say, I have two rapidshare.de folders.

In one, I have some links already inserted, but now I want to reorganise 
on some basis, so I want to delete those links from first rapidshare 
folder and enter them as such in the second rapidshare folder.

As the site doesn't provide any method for this, I think I can write 
some greasemonkey script that runs on opening the first folder and does 
the copy the links to second folder and deletes them in the first folder.

I am not able to understand how to make a greasemonkey script refer to 
the other folder page when I am in the first folder page.

Any tips are welcome.

thanks.
