Hi there. We have two types of flights on the community.
A #live:groupflights is a flight within the next three hours that is more of a “hey, come fly with me”. Gates are not assigned. All trust levels can post here.
An #live:events is more structured in which gates can be assigned and often take place a while in the future. To post in #live:events you need to be Trust Level 2 (member) which currently you are a basic user.
You may want to try to post in #live:groupflights as long as you adhere to the rules in the information thread for the category.
