Hi Pete, good to hear from you!
I've been sloooowly digging thru the Wayback and you are basically correct. In the scan bar, one has to click on the black thingies that are higher than the baseline. It will generally bring up the Forum homepage and from there one can click on the various forums/sub-forums to bring up the threads. Clicking on the threads will either bring up the messages or show nothing. It is a slow, rather painful undertaking.
Getting past 2012, there are scrolling arrows (blue) on the right of the scanning bar, with the date showing the shown scan time-frame in the middle.
Hope this all made sense
