I'm using Network Solutions to host one of my domains for the sole reason that they [sometimes] allow me to change my glue records online. However, they keep changing their site and some times they remove the ability to edit glue records. Some times they just randomly turn off the feature and you need to ask them to turn it back on. I believe the link is called "Manage Host Servers". Quite annoying.
Is there a registrar that I can move to that will let me change my glue records without any messing around?
