Okay from what I can glean, the changes that are taking place at the moment are work on software to enable the activation of new topics. What has slowed down the work is that members are posting things without looking to see if a topic exists, and thus every new submission has to be checked against the database and moved if necessary into the right slot. Their new software should make this a lot faster.
Helium are working on their debate area and this is taking rather a lot of time as well.
Things that appear will soon be looked at are feedback.
