Hi! I have a few questions regarding the API:

1. How far back does the data on getPagesPopular go? (is it a rolling chart for the last 24 hours / 7 days / something else?)
2. The getDashboardData and getPageCount methods aren't returning any data for me at present. e.g. http://www.w3counter.com/stats/v4api?key=NotInPublic&func=getPageCount&website_id=6094 returns a lovely yellow malformed XML error page. Is this a known issue?
3. Various API methods can take a URL argument, but the documentation doesn't specify what it's for or how it should be supplied. Could you enlighten me please?

Thanks in advance!
