Is there a function in rumlog. that can auto update the name field in my log with qrz.com or other adressbooks?

My log is big and i have not wrighten down all the names of the different operators, so would be great to get the names in the log without to much work.
how can i do this?

You could use this option: Menu-->QSO-->Fill Log with HamQTH.com data. However please note that it will overwrite existing information. So if you don't want to loose any data, you should use that on QSOs without any information besides call sign.
