Company Name: WarningTXT.com (capitalization optional).

We're excited to see what you come up with!
Some background: We provide text message (SMS) alerts to customers when there are potentially dangerous events in their region or country, such as natural disasters (earthquakes, tsunamis, etc), political unrest, terrorist events, severe weather warning, etc. Our customers are both travelers and people who subscribe to the alerts for their home city/region.
We have a preference for simple, functional websites in the ‘Web 2.0’ style. We want a professional feel.
We probably don’t want (but are still open to) a graphic element that is completely divorced from the text (for example, MS Windows has the completely separate wavy four colored flag/window icon). We’d prefer that graphic elements are somehow integrated with the company name.
