Posts don't expire after 30 days and there is no way to delete them when position is filled

I posted a job on hackersandhustlers.org a long time ago.

When I did I got this email from Nathan:

>Check it out: http://hackersandhustlers.org/job/513e28ec0f14f40002003899
>
>Let us know if we should change anything! It will be up for 30 days.

It looks like the deletion after 30 days was being done manually because I just checked and it is still up.   We filled the position long ago and I don't have any way to delete it.
