I am looking for a freelancer who can help me define the development and maintenance process for my WordPress forum site. The current status of the site is in progress, but it has not yet been launched.
We have created the staging site for parallel development while the live site is running. When we developing on staging site and making changes, the live site is keep accepting user content.
