Yes, if you're bid is higher Celga will put you 
second in line.  But they won't outbid their 
first client.  A non-celga bidder has to outbid 
the first Celga client before they will place 
bids for clients who are 2nd or 3rd in line.

There are several other drputy services out there 
who will help you bid if Celga already had a 
client:

These are 3 other great services you can use when 
Celga tells you that you are second in line.
