My ten pence worth, I joined after going to two free trials, yes it's a chore after a while, and it's all about coming every week with referrals for others, but be careful, as others who are there are just waiting for work from you, and will give nothing in return, as they feel its there right as they've been there so long, I must admit myself the hand full of people who where in my age range, who have all left as well, we have all kept in touch and we give work to each other more so than when we where apart of the bni, so it has had a small positive effect, but ask yourself have you got the spare time every morning to be there, have you got the money for the subscription, have you got the money for the breakfast, and make sure you have someone to cover you if you cant make it. Hope this is of help.
