is there any way to have like 10+ boards sending info to each other...
any shields to buy for this or anything? u dont need to explain to me how this is done, just a link to a tutorial or some other form of explanation would be great
Cheers,

You should be able to to this with the MaxStream XBee. Check on the MaxStream site for
an application note.

Yeah Xbee would be able to handle that. There is an Xbee shield sold at places like sparkfun electronics. It comes with an Xbee 2.5 chip that supports mesh networking.
That would get expensive quickly though.
could i put multiple shields on one arduino? like a motor shield and a xbee shield?
I have a design that integrates the ATmega168 (Arduino bootloader)
and an XBee. See Loading...
All the I/O comes out a single connector. You could do a backplane with control cards.

i dont want to bug u further, but im damn new to this, so can u explain that in more detail... or atleast link me up a site that might put me in the right direction
I do not know of any specific examples of more than than two boards communicating.
The simple examples on my site are for two boards.
If the cost of the XBee radios (~$20) is not an issue take a look at the MaxStream
XBee datasheet and mesh networking application notes. You could google for
"zigbee mesh mote" which should get you some more information.
Doing a wireless network of ten boards is an ambitious project to start with.

dont worry, im just outlining a large project... first im starting with simple tutorials, then on to the more complicated things
I would recommend looking at O'Reilly's "Making Things Talk". A lot of examples on wired and wireless communication.

iights, once agian, thanks everyone for contributing 
ya i was looking around, and found that someone recently finished making a BT shield... what do you think?
Arduino Bluetooth Shield | Finished. The kits will get avail… | Flickr]
would this be a good way to hook up multiple boards?
It could be. It is more expensive than Zigbee. An advantage is that laptops and phones
usually have Bluetooth built-in which should enable communication to the Bluetooth
Arduinos (BlueDuinos?? 
Do you know the manufacturer and part number for the radio used in the
shield?
