Batch Delete and ERROR?

I tried to reply to the last post from Chief in response to my inquiry. I tried twice - clicked reply, typed response and hit SUBMIT and got 404 Error page (??) then I tried to re-submit as new topic, in 2 different forums - same error. (Perhaps the system is down). Now, with one last try,  I am trying without the dash in title - if it posts ok, wonder if problem was due to the dash in the Subject line??

and to submit the follow-up question I had about the Custom Domain promotion......
--------
This was my followup question:

Yes, thank you. I saw the promotion this afternoon, and have already sent a Tweet to request the custom domain name because I thought it was a great opportunity.

Forgive me, but I am still a little confused about how it would work....
Does that mean that I would be starting over with a new forum altogether (i.e. I would not have been able to simply convert my current site over to a custom domain).

Would the new URL be forum.SimonSaysSynergy.com (as described in the custom domain link above) because the name would be available just like I might also register SimonSaysSynergy.org as an alternate domain?

One last question:
I could not change the domain for the initial forum (SimonSaysSynergy.lefora.com), so I concluded I would not be able to create a new forum to point to SimonSaysSynergy.com - so what would happen to the SimonSaysSynergy.lefora.com location? I would not want to continue to use it  - does it just remain in cyberspace or can it be removed altogether?

Thanks so much for your quick reply to my earlier inquiries today. Great customer service! I have been impressed - I did not expect to hear back for a day or two!
