I use MIS Spongeless replacement cartridges for an Epson R220.  As 
others have reported, some of them leak out the bottom when refilling.  
I am wondering if there are any ways to stop it from bleeding out or if 
once they start to leak they are just junk?  

I've been tossing them out, but given likely difficulty in procuring 
more cartridges would like to hold on to as many as possible.

Also, unrelated question- Paul Roark's QTR ICC profiles are neatly 
organized under a "Black and White" category.  When I make them with 
QTR they end up lumped with all my other profiles.  Is there a way I 
can get them listed under B&W, too?

Thanks,
Roger
