Picture posting is enabled for all :)
I would not go along with deleting a name because that person has not posted. However, if Dan can interrogate the database to identify anyone who has not visited the Board for (say) six months, then an email could then be sent asking "permission" to remove that name. Conversely, that would mean that the number of members would certainly drop below 300, and might even drop below 100 - would that matter?
