>But you can play wildcard in Scrabble, right?

well, not according to the '78 edition of OSPD -- I don't have the new 3rd ed.

hey! here's a cool site. it searches the 2nd and 3rd editions of the OSPD and reports on your search word; e.g.,

"wildcard" Results:
OSPD Second Edition: No

OSPD Third Edition: No
