The option to uncheck embed is already available in the back end of BBpress at: settings/forum/auto-embed links.
So the plugin I linked to doesn’t really have anything to offer (other than stopping embeds in WP).
Another ham-fisted way around this bug it to use the css:
.bbp-reply-header a.bbp-reply-permalink {display:none}
(which by the way bbpress have done on their forums)
The downsides are:
1. no numbering reference on replies if someone want to quote or link to old reply.
2. In front end profile/replies no link on each reply to take user back to relevant thread.
What do you think is best: display or not display?
