For Boston, Ma area other then SBDC and SCORE where can you go for advice so for starting a business?

I am unemployed and heard of SBI for people that are funded through M Rehab but other then that what else is available or are there any groups not super formal like you see on meetup and not ones with loads of real estate or sales people. There used to be a group with entrepreneurs who would gather for a lecture and after groups where everyone would ist each other including the lecturers and I though it was great that was in a temple in Lexington but no longer exists. Thanks for your help.
