Can a Wordpress plugin be integrated into OSSN?
Depends on what you exactly means by integration. It requires to write a OSSN component from scratch, It is not plug and play for other CMS stuff inside OSSN.
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.
