    Our main meeting 
   is
    almost always held on the last Monday of the month. 

   29 
    Sometimes due to holidays or other extreme circumstances, 

   30 
    we move it to another night but that 
   is
    very rare. Check the home page 

   31 
    of the web site 
   for
    details. The special

   32 
    interest groups meet at other times during the month. Check the SIG 

   33 
    page and visit their individual sites 
   for
    more information.

   34 
    You can also check our calendar page 
   for
    a summary of events.
