Hadn't dawned on me that hobbyists had an ID.

Most likely a dumb question. I assume a provider has to know who you are and confirm they have seen you ? What if the providers are not a member of the board. Also do we as members / reviewers have a TER ID or is that only if you are white listed ?

You can see it by going to My Reviews and opening one of your reivews. You'll see the provider ID and your member ID below it.

Whitelists are given by providers who must also be TER members. You can't be whitelisted by a provider who doesn't have a provider ID here.
