Q 85

About the Geometer's Draw Spellglyph class feature:

The spellglyph replaces any material components (other than a focus) normally required by the spell. A geometer chooses at the time of casting whether to use a spellglyph. An expended spellglyph disappears, just like any other material component. Spellglyphs are normally scribed on parchment, much like scrolls. Preparing a spellglyph requires 1 hour and the use of rare inks costing 25 gp per spell level. If the spell normally requires an expensive material component (with a value of more than 1 gp), exotic inks and treatments of equal cost must be used in the preparation of the spellglyph.
Let's see if I read it right...

A) Nowhere in the ability's description it is clearly specified that a spellglyph has to be written by the Geometer who's going to use it (just that it needs to be scribed for a specific spell). So, can any Geometer (the ability is gained a first level) use a spellglyph scribed by another character?

B) On the other hand, can a wizard with no level in the Geometer prestige class use a spellglyph?

C) If the answer to B) is no, could a Use Magic Device check be of any help?
