I have a number of outgoing private messages that have not been read. These were in response to queries from two new users, who clearly only set up accounts in order to contact me. Since their initial messages they have not returned to read my replies. I doubt they ever will.

Can a mod delete my unread replies? This is not hugely important but it irritates me slightly to have them hanging there every time I check my messages. They are no longer relevant to anything and I would just as soon have them gone.
