just replied to that, in case anyone else needs to do the same thing here's how :
Let me see if I understand you correctly, you have a main account with a page, and several other accounts, you want the other accounts to share what that page posts to their walls/pages/groups right?
You do it like this : Create a destination list, choose the wall of each of the other accounts and the accounts as well. Then create a volume campaign, in the where to publish tab choose that destination list, in the what to publish tab go to the share post sub-tab and below on the page enter your facebook page where it says Add facebook page and click Add facebook page. This will act like a rss feed basically every time you post something new on your page it will be extracted and added as a post to be shared on the other accounts. You can also set in the destination list if you want this post to be shared on other groups each account is in or in other pages that each account manages.
As for comments, go to the tools tab, click on the Comment and Like tab, click on the sources sub-tab enable Comment/Like Posts from Facebook Pages and enter you page there, it will only comment to stuff on your page now. Go back to the settings page and enter something to comment, set it to find some words, to comment on everything you can set it to find a,e,i,o,u for example and it will find almost anything, it won't comment twice on the same thing, below enter the comments you want it to make, use spin syntx to create as many diverse comments as possible. You will need to go through each of the seconday accounts and set the comment tool like this.
