hello I want to know how do I disable account creation or to allow people to view all posts without having to log into an account
Take a look into OSSN components page https://www.opensource-socialnetwork.org/components/all or openteknik's component list https://www.openteknik.com/products/all. It will help improve your OSSN.
For your demand, disable signup component
https://www.opensource-socialnetwork.org/component/view/1387/disable-signup. About the other doubt, I remember that I read here in the community that someone has already asked a question of the type.
Regards
Due to the many requests in the past for additonal features and components we have decided to develope a premium version. Features like Hashtags, Videos, Polls, Events, Stories, Link Preview, etc included in it.
