I started reading "Currently in Beta, we require..." first, and then I started reading the features, and then I was thinking "wait, what does this thing do?" and then I finally found "meTracks is an innovative web based audio player...". I think the reason I didn't find the description first is because it's at the top right of its area. I recommend putting it at the top left, swapping its place with the meTracks logo.

I remember learning the word "bespoke" for the first time a couple of years ago. My point is, that's not a common word. Maybe use the word "customized" instead.

It makes more sense to use "e.g." than "i.e." here: "Your answer must be in textual format (i.e. three not 3)."

In general, style guides advise spelling out low numbers, so replace: "All it takes...3 simple steps"

with: "All it takes...three simple steps"

Or: "All it takes is three simple steps"

Remove the unnecessary words here: "For the purpose of beta testing we will be restricting every account to 200MB"

Change it to: "For the purpose of beta testing we restrict accounts to 200MB"

Remove the space before the asterisk footnote mark in: "Limitless audio *"

Remove the space before the question mark in: "What do you get ?"

Add an apostrophe to "its" in: "so give it a go, its FREE!"

Add an apostrophe in "Amazons" in: "Unlimited space is available through Amazons S3 service."

Remove the space after the footnote mark, and add a full stop to the end of: "++ based on track size of 4MB and length of 3 minutes"

Capitalize the "S" in "Use my s3 account"
