Without a proper definition of what 'contributing' means, it is easy to take it out of context. I like this definition of SLAGA membership better: Standard Membership - free Individual Membership - $10 dues / year Family Membership - $15 dues / year Details of what these memberships represent are here: http://www.geostl.com/SLAGAPostNuke/modules.php?name=News&file=article&sid=38 (Any questions about that page should be addressed to the current set of SLAGA officers and advisors - most who read these posts)
