I can tell you because I know what client it is he has, that it does not have a logging feature. However if he would just not forget he could copy and paste it to word right after looting and running off to rest. I use the same one so that is what I do.
I used , when I was playing Roa Client, its has very similar features to zmud, numpad movement, macros, triggers, alias, and the ability to have over 100k lines in scrollback, so I would have, at any given time, at least 3-4 days of AR on my client, as long as I didnt close it
