Comments on this site are moderated (damn spammers) but most comments will be approved once a moderator reviews them. Abusive (technically or expressively), off-topic, illegal, hate-inciting or sweary comments may and probably will be deleted.
Moderators may expire old comments after a reasonable time.
If you disagree with a moderator’s decision, please appeal during one of the chat (IRC) meetings. They are announced on the forums from time to time or you can ask in the chat session for the time of the next meeting.
