I've just read the entire thread, what an interesting debate!
I'll be perfectly honest and say that its not something that's ever crossed my mind before. Mini's is an amazing source of advice and inspiration, the kindness and generosity of the members in dispensing advice and support has made it such an invaluable place for so many of us on our weight loss journeys. I never suspected anyone might have a problem with that until I came across this thread. I don't give a hoot whether or not someone pays money to SW or not, if they want to lose weight and ask for help, then I'm going to give it. I can see though that there's a massive difference from someone who wants to know a syn value or has the odd question, to someone who wants the whole plan explained to them. I've never seen a post like that myself, but they can jog on, I doubt any of us has the time for that!
I was a SW member for the first 8 months of my weight loss journey and now I follow plan myself from home. I never really got anything from group apart from a lot of clapping and a few stickers. When I started working shifts, changing groups every week was a rubbish experience. I only ever stayed for the WI and often had to drive 10 miles or so just to do that! For me in the end the decision to leave was a no-brainer, plus I could use the money I saved to join the gym. Since then I haven't really looked back, but I do think joining group initially to get the books and get your head around the plan properly is a good idea. Support wise though I've always found Mini's beats group hands down.
I always try to see both sides of the argument so can see the sacrifices the OP has made to be able to go to group. When you're struggling to budget for something and others get the same weight loss results without paying I can see where the annoyance comes from. Hats off to you though for making sacrifices and putting your health first, but honestly if you don't think you're getting much from group now then I don't think that'll change in the future. At least it didn't for me.
Anyway, sorry for the rambling off-tangent post.
