Wow...you bothered to dig up and respond to a 13 year old thread ? That has to be some kind of a record.
have not been active in forum lately, but stumbled in today - I will try to clarify a couple things based on what I have seen before when I was actively posting in the forums regularly.
this dynamic popped up a couple years ago and I recall stumbling across some old threads in what WGT labels the ACTIVE Threads list on the right hand side - so players may not necessarily be digging anything up - but the manner in which WGT designed the links to dig up old topics or threads despite being inactive for years - is more often the factor that prompts old threads resurfacing - unless you are one of those types that purposefully goes digging for them.
Now there are a few topics that new members might search for - but I would wager most of these old inactive threads are being pulled up by WGT and mislabeling them as active.
Another possible factor might be because someone that is still active went thru their old history and deleted or removed something they posted before - so it updates the old thread while not showing any new entries being made. That would then prompt it to show recent "active thread" status despite nothing new being posted.
food for thought.
