Substantial Communication

GURPS Psionic Powers 14, lesser version of Affects Substantial for Insubstantiality
==possible source of confusion==
The intent of this enhancement is:
:use any of your mental abilities (psi, magic, etc.) to communicate with the real world
This is at -3, requiring an extra +40% enhancement to remove it for advantages (which would require TEFE for spells)
T228's Insubstantial Beings Affecting the Material World makes a statement about "information effects" which might be considered to overlap:
:Information effects, illusions, etc., that don’t give any subject a chance to resist can usually be used freely while insubstantial – for example, nothing prevents an insubstantial wizard from working a divination – but if they have an offensive use (e.g., the Death Vision spell), then they count as “mentally resisted” for this purpose.
The term "used freely" might simply mean there is no -3 penalty: the lack of a resistance roll could mean you're not interacting directly enough with a substantial target to incur a skill penalty for use. However it still might require either the +100% enhancement (or at least the +40%) to use if it involves gaining physical-world information.
"Information" and "Communication" could be very different ideas though.
