@beltran I come from meta.discourse.org after knowing your forum has the solved (accept) post feature. I am using this plugin https://github.com/shivpkumar/Solved-Button. However, this plugin lets everyone accepts a post as a correct answer.
While looking at your forums, it seems that the plugin only allows OP or Moderator/Admin accept a post. Is it the plugin open source or free in any chance?
The plugin we use also allow users to mark the post as correct so probably don't interest you.
Thank @tomasp, but who is the "users", anyone or the OP? I tried to go to another topic but I don't see "Mark as correct" button.
The plugin I am using allows everyone mark a post correct, even a visitor without an account.
