There are no more archives.
Archiving the forums every six months or so was necessary due to the limitations of the old software.
All archived mileposts have been re-incorporated back into their respective forums. Simply do a Search in the desired forum (or all of FlyerTalk, if you like) and make sure you search from the beginning (as opposed to the last 10 days, for example).
I hope this was of some help to you, letiole. If not, please let me know and I will attempt to clarify what I wrote in this milepost...
