Smidge of terminology drifting going on ... no big deal.
You bought the XPH, why?
d20srd.org has it, plus the good parts of D&DG and Epic and Unearthed Arcana.
You bought the CPsi, why?
Well OK, I bought them both too, so I'm calling no kettles black, I'm burnt.
back on topic ... that's an early build, historically very useful.
Srd Slayer gets rids of killing an Illithid, and the 10th level is a little sketchy anyway.
Anarchic Initiate still gets kudos, it's better than straight Psion. Recharge is easier with it.
But it's not the end-all of the build, so ditching it can work.
PhaeXY said Ardent because of the 3 MLs lost to the Ranger, Fighter, and 1st Slayer level.
KellK said Mind's Eye because that upgrade, impacts this direction too.
iirc - the arguments about how Share Powers + Divert Teleport were later in that thread. And now lost to WSoD, or the latest numb-skullery.
d20srd says:
Range: Medium (100 ft. + 10 ft./level)
Area: A circle, centered on you, with a radius of 50 ft. + 10 ft./level
Effect: Diverts the teleportation of any object or creature whose weight does not exceed your maximum load
Similar to detect teleportation, except that you know the intended destination, and you can divert the final destination of any teleportation attempt made by others within the area. This is an immediate action, like manifesting a quickened power, and counts toward the limit of one quickened power per round. You can manifest this power even if it is not your turn.

I bolded the "you", man this is a little confusing.
