Okay, today a prophet edifies, exhorts, and comforts. What else does a prophet do?

Ephesians 4:11-12 tells us what ALL spiritual offices do:

And He Himself gave some to be Apostles, some prophets, some evangelists, and some pastors and teachers, for the equipping of the saints for the work of the ministry, for the edifying of the body of Christ.

So a prophet equips saints for the work of the ministry in order to edify the body of Christ. Nothing crazy or fanatical there. You don't have to be afraid of the gift of prophecy.
