Crystal Reports announcement channels ?

Hi,

Is someone know how to get the last news, available downloads and updates about Crystal Reports ?

Are there some RSS ? Newsletter ? Blogs ?

Is the Check for Updates in CRXI R2 working ?

Because when I add SP2, I checked for updates but the Installshield Wizard didn't notice the SP4 (The SP4 was already available at that time)

Thanks for your future answers,

Phil
