The IOS will not allow you to put both commands in.
Router#wr t
<snip>
!
interface Serial0/0
ip address 1.1.1.1 255.255.255.0
encapsulation frame-relay
ip ospf priority 0
!
router ospf 1
router-id 1.1.1.1
log-adjacency-changes
network 0.0.0.0 255.255.255.255 area 0
!
<snip>
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#router ospf 1
Router(config-router)#neighbor 1.1.1.2
Router(config-router)#do term len 5
Router(config-router)#do sho run | be router ospf
router ospf 1
router-id 1.1.1.1
log-adjacency-changes
network 0.0.0.0 255.255.255.255 area 0
!
Router(config-router)#int s0/0
Router(config-if)#no ip os pri 0
Router(config)#router ospf 1
Router(config-router)#neighbor 1.1.1.2
Router(config-router)#do sho run | be router ospf
router ospf 1
router-id 1.1.1.1
log-adjacency-changes
network 0.0.0.0 255.255.255.255 area 0
neighbor 1.1.1.2
Let me ask you this, in what situation would you need both commands
applied?

Brian, in regard to the following, why not?
"you can not put the OSPF 'neighbor'
command on the spokes if they also have the "ip ospf priority" command
applied to the interface."
