I'll second this feedback, and add one other minor point: I wouldn't use the acronym (or is that an abbreviation since it is not pronounceable?) "IaaS" as part of that signup form. I do a lot of work with SaaS and it took me a minute to figure out what you were talking about. (It didn't help that in your chosen font upper case I and lower case L look quite similar. At first a thought you mean "logging as a service" which seemed like a strangely narrow expression.)

For what it is worth, I would either spell that out, or even better, change it to something a little less jargony, such as "cloud based services" or something like that (which is still a little jargony).
