This is a very good thread. These day many of us doesn't read hard copies.
I came across a problem. many of the links posted in http://www.o3wall.com
are not working. (The message "Sorry, this document doesn't exist." apears and it seems that the document has been deleted in the site) for example I tried Sasara Charika byTharanga Disanayake @ http://www.o3wall.com/forum/topic/110
Can somebody please post some other links such as Mediafire.
