Erm, that's because certain forums on here are for people who are qualified in that trade!
It's really helpful if everyone fills out their qualifications etc, then it stops all confusion.
Consumer geek is the forum for non pros to post on, and chit chat. Nobody minds on there if you aren't a nail pro, therapist or hairdresser.
On the trade forums, we get lots of consumers try and get info so they can go into wholesalers and buy pro products. It would be really dangerous for us to collude with this behaviour, lets face it, we don't train because we don't need to.
I'm sure a mod can post up a link to the forum rules, which everyone is supposed to abide by. Worth a read, then you can post away, knowing you won't get flamed.
