Can they go all in?

As I checked out a book at the Collinsville Memorial Public Library yesterday I noticed a flyer advertising an event to be held in the community room that afternoon. Texas Hold em card game from 2-5. No money involved.

The Collinsville library has arguably been the best run tax payer supported entity in the city and always on the cutting edge of what's new and desired by the public. The director has a blog! The library has been wireless for a couple of years now! And this is why, knowing this, the poker announcement stopped me in my tracks. Aside from the internal debate about whether or not to go downstairs and watch or even play a bit, what I wondered was how this Texas Hold em fever could play out as local fund raisers.

I seem to remember an Illinois non profit group setting up a game night and then finding the laws prohibited it. Or, the laws denied monetary payouts. Maybe someone here knows the details. It might be interesting to learn what can and cannot be done with Texas Hold em nights because it looks to me, in a New Year's prediction mode, that this could be the next bingo or trivia night for charitable organizations to raise funds. Would this game played for fun and fund raising by American Legions and PTA's etc violate gambling laws?
