The best places for validators and stakers to meet and discuss node-running and staking choices is the #node-runner channel on the Radix Discord;
Various node-runners also run Telegram groups for their validator or other topics. Definitely ask which ones to join when you’re in the main Discord or Telegram groups!
There are also a multitude of websites created by Radix validators that provide services and other really interesting statistics. To find our more about these websites, see How do I discover dApps and tokens in the Radix ecosystem?
For general queries and discussion, you are also very welcome in the Radix Telegram channel.
