It correlates to a domain for a site I'm in the process of building. I haven't registered the brand's trademark yet, so I'm unable to claim the Twitter username based on that criteria. Seems like the only route they provide for this kind of thing.

I believe if you have the domain name you should be able to get the twitter handle. You can always just submit for a trademark, that's easy and cheap.

I've never registered a trademark before. Is there anything more to it than paying the fee and filing the paperwork for a business that's not yet operational?
