Let's say you've jumped in and created a client. You want to see if it works with the CTP. What's a good path?
First, the PI server is named jmaytumwin2k8 (hi, John!). It has the usual suspects -- sinusoid, sinusoidu, cdep158, cdt158, and so forth. I've also created two tags to test data entry: InsertTest1 and InsertTest2. Since we don't have your user ID in a secure, federated kind of way, I had to open these tags up to the world for read/write access. So you can get your data in there, but look fast and don't expect any great degree of integrity.
