Anyone know why when I am attaching something in topic its showing new user cannot do it
Hey @vibhuti123i - Discourse, the underlying forum software we use for the Explorers Hub has a number of Trust Levels for users. New Users start at trust level 0, and move up as they engage more in the community.
Trust level 0 users cannot post attachments. This is partly so that the system can catch spammers who may create accounts solely to post unrelated content on our community. I have just upped your trust level to 1, so you can post attachments.
More on these trust levels can be found in Discourse’s blog: https://blog.discourse.org/2018/06/understanding-discourse-trust-levels/
