I think there should be a section on forums where users can post questions to admins directly. Unlike PM'ing or anything, all admins could respond fast so it would be like sending a PM to all the admins. All threads made under this section should only be seen by the OP and admins so no normal user can see it.. It could be a place where users can post feedback, or a place where people can ask questions about certain topics like Donating or Technical issues to admins directly.
Thanks for reading.
