Possible SLARP Problem

in CCNA & CCENT
I had another problem configuring 4 routers and getting them to talk to each other. When i do the sh ip int brief command, under the method column, it says SLARP. Usually it'll say "manual", but this time it says "slarp". My question is, would this in any way stop me from connecting to other routers?
Another question is, how could I change it back from "slarp" to "manual" again? I'm going to take a final on these routers at my college next week, so any input would be DEEPLY appreciated. Thanks.

The biggest risk in life is not taking one.

It should not effect you connecting 2 routers.
