To create a new folder I use :
mkdir folder (create folder) sudo chmod 777 folder (allow all users read/write access)
How can this folder be shared between other PI's on network, so it can be written to / read from other machines on network ? Machines includes Windows and other Raspberry PI's but I'm not too worried about Windows if that is too much hassle.
I could perhaps use Tomcat server with simple form but this seems overkill for this task.
Thanks to @Joseph suggestion samba did the trick.
However after running initial samba installation I received error :
The following NEW packages will be installed: samba samba-common-bin tdb-tools 0 upgraded, 3 newly installed, 0 to remove and 0 not upgraded. Need to get 6,081 kB of archives. After this operation, 36.1 MB of additional disk space will be used.

After running "apt-get update" and re-running installer everything worked fine. What operation does "apt-get update" perform in order to allow installation to complete correctly ?
Also I found this tutorial helpful, (mentions mapping network drive). As I have multiple PI's on network I connect using custom hostname rather than one specified (raspberrypi) http://www.maketecheasier.com/turn-raspberry-pi-into-file-server/
