From the explanation of Discourse trust levels that I already sent you:
Trust Level 1 – Basic
At Discourse, we believe reading is the most fundamental and healthy action in any community. If a new user is willing to spend a little time reading, they will quickly be promoted to the first trust level.
Get to trust level 1 by…
- Entering at least 5 topics
- Reading at least 30 posts
- Spend a total of 10 minutes reading posts
Users at trust level 1 can…
- Use all core Discourse functions; all new user restrictions are removed
- Send PMs
- Upload images and attachments if enabled
- Edit wiki posts
- Flag posts
- Mute other users
