Update: I am happy to say that today we begin the big Marketplace move. Since we did not gain the critical mass of volunteers required to effectively move/copy marketplace threads into the new structure, we had to come up with an alternative solution. A custom solution was developed that allows for invisible processing of threads without having to move them all at once. It will take more time, but rest assured that we will have a team of people who will hopefully be able to go through over 16,000 threads efficiently (keep in mind that each thread has to be looked at individually).
I, for one, hope that everything will go through in a smooth way and none of you will experience any inconvenience in the process. In the meantime, you may continue to use the advertising forums as you normally would as it will not impact our work behind the scenes.
Wish us luck!
