No text chat whatsoever is allowed during the Race and Qualifying sessions. Chat during Practice and Warmup sessions is allowed, but please keep it related to the event itself.
For oval racing events, Race2Play does allow the use of the quick-chat messages for Pit-In and Pit-Out during the race session.
Voice chat is allowed during the Race session (but not Qualifying). Anyone connecting to the voice communication servers during events does so under this assumption. Please keep voice chat related to the event itself.
