There is a TrainingPeaks Virtual Discord server - which was working great for couple of years, however Discord now wants the user's phone number in order to allow posting. I believe this is a security issue - I should not be forced to provide my phone number to unrelated 3rd party in order to discuss TrainingPeaks product.
It would be much better for TrainingPeaks to host a dedicated web forum (ex. using Discourse like many other similar products do).
