[WriteLog] Log correction question

[Gary AL9A]

I recorded the WAE SSB contest last weekend and am now reviewing the log to 
correct typos if I find any.  However I'm not sure what will happen to the 
scoring if I correct a callsign.  All but the last few QSOs were sent out as 
QTCs during the contest.  If I change a call in the log, should I also 
change the same call in the QTC batch I sent or leave it alone?  If I 
correct the QTC the receiving station will have the wrong call in his log 
and not get a match on what I sent him.  Any suggestions?
