What topics can I ask about here?
Please look around to see if your question has been asked before.
A question should be about Buddhism – any school of Buddhism – perhaps about doctrine; or about practice; or about history, culture or art.
This site's community developed a slightly unusual set of policies for questions, unlike those of many other SE sites – for details see the https://buddhism.meta.stackexchange.com/q/1558/254
If your question is not specifically on-topic for Buddhism Stack Exchange, it may be on topic for another Stack Exchange site. If no site currently exists that will accept your question, you may commit to or propose a new site at Area 51, the place where new Stack Exchange communities are democratically created.
