authorisation before prices can be seen

[ctbhost]

i have a website that is a wholesale website, and have added the login to see prices MOD

but peoplw can still register and then login and see pricing.

i have an idea to get arround this that i think should be simple to apply but i cant seem to work it out

My idea
1. create a customer group called 'NO PRICE'
2. when a person registers they are assigned to the 'NO PRICE' group
3. all products that are added are automatically given a value of $0.00 for the 'NO PRICE' group
4. the administrator themn needs to authorise them - to do this they then chane the client to the retail group so they can then see the prices

my question
1. how would change the default group - i cant seem to find where is is set.

i have tried several things biut cant seem to get it to work.

can anyone tell me what the 2 below field are used for
customers_group_name - this is the group name
customers_group_id - this appears to be the group id but when the group is changed in the admin area it doeant change this but only changed the customers_group_name

any help would be appreciated

You need to use display prices per user group type of mod.

Then assign everyone to a default group (no prices) - then WHEN you approve them - then change the user group to the WHOLESALE group (that shows prices).
