Shaping questions

[jcorey30@yahoo.com]

I have a bunch of questions about shaping magics, and I ma hoping you 
guys can help me.

1) Should the College of Shaping Magics Counter spells affect invested 
items?  Should they remove or temporarily disable the investment?

2)Can a shaper use The Ritual of Investment (32.3 the generic one) to 
invest a spell from another spell caster? from another college? What 
about using his own R-6?

3) Could a string Golem know spells from more than one college?  Or 
would he need the magician skill?

4) I kinda need your advice my saturday.  thanks!
