Hello,
Google groups hosts discussion forums where you're likely to find information like service status updates and release notes, and ranging from book recommendations to creative shortcuts.
For technical issues, try Stack Exchange sites. Stack Exchange uses a popular question-and-answer platform and it hosts a number of sites, including
Stack Overflow and
Server Fault. Stack Overflow is generally for developers and Server Fault is aimed at system and network administrators, but anybody can ask and answer questions on these sites.
Regards,
