Assuming Anki Forum is using Default Settings for Trust Levels:
Users at trust level 0 (New User) cannot …
- Send personal messages to other users
- “Reply as new topic” via Link button (UI removed)
- Flag posts
- Post more than 1 image
- Post any attachments
- Post more than 2 hyperlinks in a post
- Have actual links in the ‘about me’ field of their profile (will be silently and temporarily converted to plain text)
- Mention more than 2 users in a post
- Post more than 3 topics
- Post more than 10 replies
- Edit their own posts after more than 24 hours
Admins can change these limitations by searching for newuser and first_day in site settings.
Even if Anki domains were whitelisted, it would still count as hyperlink and fall under trust level 0 rule: New User can’t post more than 2 hyperlinks in a post
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 (hyperlink restriction lifted)
