Matt, how long have you been frequenting dispensaries? Have you ever became a member/patient of a collective since you got your card? Reason I'm asking...when you complete your paperwork, you are asked (by most) if you plan on cultivating cannabis for the dispensary and/or donating your time. So that pretty much implies that shops get at least some of their meds from patients.
As suggested, I'd take down any personal information and change your username. Based on the title of this post, fear DEA agents that lurk behind computer screens, looking for "easy catches"--people who can be added to their list MJ growers, even if they did nothing else.
BAD PUBLICITY FOR YOU!
Try calling up dispensaries/delivery services and ask them if they accept (new) vendors. Then get details from there.
