Does your church train for altar work?

If your church has an altar, or anything akin to it (ie a place where 'seekers' come to pray), does your church have altar workers?

Is it a free for all, where anyone can come forward and pray with the people at the altar?

Or do you have specially designated people only who are allowed to do that?

And in either case, does your church give instruction and training on how to minister 'in the altar'?

And IF so, could you describe that training? Also, has the training been effective?
