Yes, yes, indeed. Illegal events are certainly to be frowned upon; would certainly not want to ruin it for other home brew clubs, agreed.
I can assure you that CHAOS has explored the Illinois Liquor law in detail and has participated in more than a couple fora, discussion, and meetings regarding such events before inviting people.
We just changed websites but I believe our new website still has the discussion regarding "events" if anyone would like to find out more.

Thanks for your concern!
