In addition to the other great answers, I'd like to repeat my suggestion from comments:

Encourage to write a (good) question on Stackoverflow.com

Why?

• You may need to answer a support question only once and you can always reference it.
• Other users may have answers, and thus shifting support effort away from you.
• It will make your lib known (and understood) better.
• It is great community which most probably will have some knowledge about "Y". (Thinking is: You won't be the only one telling them "this is about Y, not X" )
• ^^ Just to name a few.
