When a web site has a "Beta Version' what does that mean? The Virtual Stock Exchange has one that's a ton easier to use than the regular version. Is it a temporary thing? I'd hate to load up all my virtual accounts and then it disappear in 6 months. http://vse.marketwatch.com/Game/Homepage.aspx
It's a test version..... dunno about the rest. I used several Google Earth beta versions before and each time I downloaded a new version it kept all my info intact.
You start with alpha and then go to beta there can be numerous versions under these and eventually you get to a finished product. Chances are your info will be kept intact and eventually they will release a final product for use (version 1.0 etc) that is no longer beta but is complete. usually betas since they are a work in progress have some issues/problems etc. that get worked out by the final version (which will still have problems!)
