Tried HBRelog first. Was easy to set up and it ran flawlessly out of the box. I ran GB2 on one toon for an hour, had it log off and idle for 30 minutes, then log on to a different toon to do Archaeology for an hour. Ran without a hitch and looped back to GB2 at the end. I've got it running that loop for a much longer time now.
This thing works great. I'm probably just going to keep using it unless it ends up not doing something I want it to do. At that point I might try ARelog, but I'm in no hurry. HBRelog seems to do what I want it to do for the time being. Thanks for all the replies.
