This is mainly inspired by this Game Development SE Meta discussion.
Currently, it takes 5 votes to close or reopen a question. Due to our low user count with the privilege to cast votes, it is nearly impossible to actually reach this threshold. So my suggestion would be to follow the example of the Game Development community and ask for a reduction of the threshold to 3. According to this question, Stack Overflow already did this. However, it might take a long time until it gets changed here. In the meantime, I would simply use my mod privileges to apply the corresponding action. Additionally, I would also take flags into account when counting the votes.
Let me know what you think.
