Since the number of members of coin-discuss mailing list isn't publically available the we can do is estimate the numbers based on the numbers of posts to members ratios for OpenSG (19.24 posts/member) and !OpenSceneGraph (19.79 posts/member) to give around 170 members on coin-discuss.  While this may be an under or over estimate of numbers it is likely to be an over-estimate as the mailing list activity on coin-discuss dropped between 2004 and 2005 by 19%.
