Purchase an Annual Registration to the All Seeing Eye
 
The All Seeing Eye is shareware, you have 21 days to evaluate the product after which you must register if you continue using it.  
 
When you register you also get access to a bunch of new features:  
 
unlimited buddy list (unregistered version is limited to 4 buddies) ability to use wildcards in player searches (to search by clan tag for example)  
real time server monitor that lists team scores and time remaining (for games that support this)  
guaranteed access to the scanner server - during peak hours the load on the servers often gets too high to serve everybody  
ASE can be purchased through several registration services, each of these services accept different payment methods and also have different additional fees (manual processing fees/sales tax), so you should check them all out to find the best one for you.
