Yamaha DTXpress/DTXplorer/DTXtreme

Hi Guys,

In my quest to get more info on the DM5 ive been offered i went to 
the Alesis yahoo users forum and they are in undated with unwanted 
messages as well .So it looks like somebody is hitting all yahoo 
groups ,So is there not any way yahoo can deal with all this or is it 
because it is open groups that are vunerable.

Lee.
