I joined online last year. For me it was a complete and utter waste of money! I think if you are new to the plan it is better to attend meetings for at least a month.
I attend meetings now and never use the online stuff (which is now part of my weekly meeting fee) apart from entering my weight each week. I much prefer this site and using the cookery books you can buy in class.
IMO the SW online site is no where near as good as the WW online experience. I remember being very underwhelmed when paid all that money and saw what I got!
