With changes to OMNI's viewing audience, I've been compelled to delete or edit posts. This is proving to be time consuming, is there a short-cut that would allow me to delete ALL OMNI posts and start fresh?

Here is my current technique:

Use "advanced search" to find posts by "me" in "OMNI"

Open each thread, find my posts

Click to "edit" then click "delete"

Click "delete this message"

Click "back" to search results

Repeat

Is there an easier way?
