OR Society/OR Grps/OR Bodies

Hello all

I am a working profesional, and was eager to know if there are
professional OR grps/bodies which I can join/attend their
workshops/seminars.

Are there ways with which professionals can keep themselves updated
with the latest in OR area? Are there univ which offer accredited
online courses/etc.?

I hope there are certain leads from the readers.

Thanks, and Regds
Dave.
