For any new users trying to post memes and facing issues, it i because you are at Trust Level 0 and therefore cannot add attachments or post more than 1 image. This is one way that helps us deal with spam and scammers.
BUT good news is that reaching Trust Level 1 is very very easy.
Get to trust level 1 by…
- Entering at least 5 topics
- Reading at least 30 posts
- Spend a total of 10 minutes reading posts
(Note: Topics are threads, and reading 30 posts includes original thread posts as well as comments. So as long as you read at least 5 threads, you can be on your way with sharing all the Cardano memes you’ve created! )
