I QSL direct and via LoTW and import this to QRZ. So if you QSL via QRZ I will confirm there also. Most of the time I don’t send out paper QSL cards, but I do like getting them and if I receive one I will reciprocate. I also sync LoTW to ClubLog and will respond to Online QSL Requests there.
My first few years as ham I didn’t really keep proper logbooks. I also work mobile a lot of the time so I can’t log while driving, although if I am driving and you want me to log QSL I’ll happily pullover and log in my LogBook software on my phone. Hopefully I can add some more contacts to it.
Below you can view and/or search my logbook. You can also see the number of countries I’ve worked and that I have confirmed:
