I have read the comments by people experiencing the same problem and none of them resolves my specific problem.
I purchased domain credits to make my domain http://www.topdollarnews.com work with WordPress. I already had Google Apps with topdollarnews.com and liked it. When I changed the nameservers to point here, I suddenly lost Google Apps and my email no longer worked.
So I phoned up Google Apps support and they suggested I just put it all back to them and merely forward my domain to the http://topdollarnews.wordpress.com domain.
That is what I am currently doing but it's just a bodge really because ultimately I don't want "Wordpress" in the URL.
I've been reading comments and they say YES, you can get Google Apps to work with WordPress, while having WordPress look after your domain.
I don't care about Google Calendars, Google Docs etc. I just want Google Mail to work with my topdollarnews.com account. It's essential to have an email contact for your account.
It seems to be a question of changing the nameservers to point here and keeping the MX records as Google. But I don't want to do the wrong thing and lose all my Google settings all over again.
Can someone out there please tell me how???
And then I can do the same with my other WordPress account.
Remember, I am an idiot, so you need to tell me in language an idiot will understand!
