why GUNH and not GUNAIC?

Another question along similiar lines:

Why is the nom sing GUNH and not GUNAIC (C=ksi) as suggested by the stem 
GUNAIK in other forms?

Also, I heard talk a couple of months ago about making an out of 
copyright edition of LS available in electronic form. Does anybody know 
about this? Are there any moves to make some out of copyright editions of 
Greek grammars available at e-texts?
