This is a support forum, and generally, to support people, you need to know as much info as possible. The way replies work, the emails sometimes do not contain everything, and code is certainly not formatted properly in them.
By forcing you to reply here, it prevents duplicate replies, replies without good content, and responses that are just plain wrong.
