The Forums are a place for players to interact with players for the vastly major part. Staff is obviously allowed to interact, but it's not necessarily part of their functions, including Moderators. Questions for the Staff are suited to be sent as a PM to a member of the appropriate Staff group, not posted in a thread. An answer might come still, but it depends on someone that has the answer not being busy with something else.
This Forum section even more so is a place that from the very beginning has been a section for players to assist players. Staff can intervene if they know the answer and no one else is assisting, but it shouldn't be something counted on or expected.
And lastly, this question specifically can be answered by Developers, perhaps QA. But considering the players' track record, I wouldn't want to be a Developer answering it, just to be attacked later if it takes longer than expected.
