BuddyPress.org

It is not a BuddyPress issue because the group forums use bbPress.

bbPress doesn’t offer a preview button in their core; if you want one, ask the bbPress developers to add it to their roadmap.

Or ask someone to port one of the bbPress preview plugins (like I mentioned above) to BP.

I closed this thread initially, but reopened it for those who might want to consider a port.

Please do not divert this topic to a debate about bbPress vs. BP’s use of it, otherwise this thread will be closed.
