Look. This place is incredibly useful for many people, especially in the electric bass world. My many posts here have been in the bass guitar realm, where everyone is still discovering things about an instrument that's only 50 years old! Most electric bass players don't have a professional teacher they can go to for advice.
Here in the 'classical' double bass arena, forums are not the best place to get advice because there is greater access to professional teachers that you can talk in person to.
I've never made the generalization that everyone here doesn't know what they're talking about- that's simply not true at all! However when I browse threads where beginners are asking basic advice and I see so much terrible advice with only a few great suggestions it's not encouraging.
Mr. Warburton- From your profile you seem to be a successful professional. Do I think everyone here's inexperienced? Of course not! However when a student like the poster has access to a professional teacher that they can talk to in person, I don't know anyone who wouldn't prefer asking them for advice versus people on the internet that you have to take your chances with.
Despite your professional resume, I find cursing at me to be very unprofessional. It goes to show how much easier it is to attack people online that in person.
'MDEbass'- If you want any tips in a concrete manner- start slow, use a metronome and use your ear! I'm sure your teacher would tell you the same thing in a more thorough fashion.
