When you delete an MX record in the DNS Manager, you get a confirmation page:
Quote:
DNS Manager ยป Remove record
Are you sure you want to delete this MX record?
[ Yes, delete this sucker ]
For A records, the "Remove record" part tells you which record you're about to delete, so that you don't accidentally confirm clicking the wrong "Remove" link. It would be helpful if this were also the case for other record types. I'm currently doing a bunch of MX record changes, and I get the generic "Remove record".
