An make sure you are sharing the .txt type files ( enable the text category of files.)
I'd say this is a better method
Make four new txt files and name them as follows :
(((Message))) Please share
(((Message))) I have mxmoniter
(((Message))) You must have atleast 10 files
(((Message))) Otherwise you will be ignored
Now share them.
Make sure you have the "(" character as it usually hits the top of your list then...
Cheers
