Hi Carl,
We are happy to hear that you are staying with us. In regards to your question about pointing domain2.com to domain1.com/blog/wordpress, it is certainly possible yes, however it would take a bit of server trickery on our side to make domain1.com totally transparent so the request actually looks as though domain2.com and domain3.com are real domains and not just simple redirects.
All you would be required to do on your part is make sure that domain2.com and domain3.com are pointing to the same name servers as domain1.com. Then you would just need to put a ticket into our support desk at
https://ccc.webhsp.com with the two domains you wish to add and reference this forum post (
http://forums.webhsp.com/index.php?showtopic=95) so we are aware of what you are needing (save you having to type it all out again) and we will be happy to set it up for you.
As for your question in regards to the account switch over, that is something that you would need to discuss with our accounts team on. If you could log a ticket at
https://ccc.webhsp.com we will certainly take a look at your request.
If you have any more questions or concerns Carl, please let us know.
Thanks!
Mark
