Sheesh!
I did do a search. And I read 31 pages worth of posts on this AKA board (not every single one, but a good chunk), and kept seeing how folks were told to search after they asked a redundant question. I did find out the name of the Philly chapter, but was unable to locate a website on a regular search engine. I definitely haven't been able to find out about any good hygiene groups. My first post, and I get chastised.
Sorry to disturb.
