Assalamu alaykum Br. There are aalims and muftis who have the authority to reply those queries from OP. Our elders advice us to limit ourselves to dawah and fatwah giving must be done only if you are a mufti. Let me quote an incident. Once I consulted an aalim (who is a great scholar, fantastic arabic language skills, great speaker). This great moulana directed me to a less known mufti of the same madrasah. So there is a protocol. Our elders expect strict discipline in following this protocol.
