The restricted access is the best way to go, in my opinion Admin has got it bang on right. As for people who are wondering whether to be members of SA, and want to see the thread for advice I say, well its UKP not UKSA so make your choice and take the plunge like most did before that thread even started. There are other resources out there on G to help you make that decision you can use tho.
Thats part of the excitement, and those that say they are concerned about chucking 50 quid or so at a month, then ask yourself, are you really a "sugar" daddy anyway
