I think I'm missing something - how would sending an email to a Yahoo account help with accessing its calendar API?

hi,
if you know other way than please let me know

[Ulf Dittmer]

Searching for "yahoo calendar java api" or some such phrase yields many results. It would be interesting to know where, exactly, you looked on Yahoo's developer site, and came up wth nothing.
