Re: Tikiwiki wikiplugins help for googlecalendar
Hi balloon_umich (hi Gary) & welcome to Tikiwiki Community! 
To complement Gary's answer, you can also try installing mods by hand using the tgz file from mods.tw.o itself.
http://doc.tikiwiki.org/Mods (see "Manual install" info)
I haven't tried that specific mod myself. good luck, and report back if you find any further issues.
Cheers
