I don’t know if you know this rule, but it’s a thing: Don’t revive old topics. If no one has posted in a thread for a long time, that means the conversation is done and need not be continued. The reason this unwritten rule exists is because by reviving a dead topic, it can take the spot of a newer, more important topic on the front page. There are a few exceptions to this rule, such as a problem that was thought to be resolved has resurfaced, or it’s a thread that is meant to have updates as needed, such as Aurora Veil’s hero guides, or @Filadae_Djaq’s badge origin topic.
Other than that this is the rule of the forums.
