Forum Google bot only views calender
 

As the title suggests .. whenever google crawls my site .. all it ever accesses is the calender .. this is no good for indexing my pages .. as I assume it is the primary indexing tool for where I am hosted.. perhaps my forum pages are not getting propagated as much as they could be ?,.. how can I change this .. and .. if yahoo and others are viewing my forum normally, should I be concerned that google isnt ?
