The psionics.info is missing a lot of powers from the game. Also, it includes non official powers? I wouldn't use it as a reference for psionic powers.
The Master Psionics List found here on these forums is much more comprehensive, in my opinion. But then again, I'm biased as I'm the creator of it. (See my signature for link to information about it.)
The Astral Construct workpage on the psionics.info site is nice, but it's also missing all of the bonus menu options for the Erbauer (Astral Constructor prestige)?
