I know I can share data through the export, but how do I share data through a scorecast if the last export wasn't completed?

I know how to do it with basketball (sc:is #), but how do I do it with baseball?

It is done the same way with all the sports. Options -> Data Sharing -> Get from Web Database. For Customer ID, enter "sc:XXXX" where XXXX is replaced with your customer ID, and your password is whatever you have set on the Options -> Admin Website screen.
