While I've also seen the slow posting, it's at least reduced significantly, if not gone away completely, since you made a change at some point. The only time I see slowness now is when I bring up the site the first time after I've not for a good while, like overnight. This steers me towards DNS.

I just did an nslookup at home and found that it took quite a while for "empegbbs.com" to load. It felt like less time than the initial browser load delay, but there's still definitely something wrong with the DNS records. I'd say that you need to fix that first before you can definitely say that it's something else. Not that two things can't be happening.

I understand about the registrar problems, though. They can be a pain.
