I have been around long enough to have a pretty good grasp on threads that will remain active, and those that will obviously be deleted or closed.
However, it appears that there are new mods in town with trigger happy fingers closing threads left and right that can be beneficial for both members and the forum owners.
Sure, some threads may seem redundant when people start talking about the design changes etc, (positive or negative), but deleting every one of those threads will only cause members to feel muzzled.
Many threads can lead to heavy debate, but that is what makes (made) this forum a fun place to hang out and learn from peoples difference of opinions.
If you take away the freedom to express our opinions, then you (forum owners) may eventually be running a pretty empty forum in a very short while.
