I use Logic9 as my logging program and when entering a new call, the program will tell me at a glance that the new call is a LOTW user thereby relieving me of the hassle of issuing a QSL card through the mail for confirmation. When I see LOTW on a new call, I can just forget about the hard card. There is a list of LOTW users I believe on various sites and perhaps the ARRL site. Can this be indicated on a user page that that user is an LOTW user? The bio of many hams do not indicate that fact unfortunately.
