Yeast 2-hybrid artifacts

I'm a grad student at Berkeley who recently spent a considerable 
amount of time characterizing a yeast 2-hybrid-cloned protein-protein 
interaction only to find out through the grapevine that others had 
cloned it using totally unrelated baits :(  Another of my candidate 
clones (which I had been excited about because I found a considerable 
body of literature linking it to the process I'm studying -Hah!) was 
also cloned by someone else who was working in a lab down the hall, no 
less, with another unrelated protein. Both of these clones even passed 
more stringent tests of interaction, like GST pulldown. Have you had 
similar exasperating expieriences? If so, my question is this:
	Does anyone out there know of an internet resource which contains or 
might contain a list of commonly encountered artifacts in the yeast 
2-hybrid screen? Is there a 2-hybrid newsgroup? If no such resource 
exists is anyone interested in creating one? I'll show you my clones 
if you show me yours! :)
											Thanks $ your time,
