I have been doing some research on the future of the DSM (Diagnostic and Statistical Manual of Mental Disorders). This is the "bible" of psychiatric diagnoses. Psychiatrists use it to describe, categorize, and code pshychiatric disorders. Insurance companies rely on it when determining what is a legitimate psychiatric diagnosis for determination of coverage of treatments.
As many of you know, one of the most frequent arguments used by those who discount the existence of gaming addiction or pathalogic gaming is that it does not appear in the DSM-IV. The biggest reason for its absence is that the DSM-IV was based on research that was available up to the year 1992. Research on gaming in general was in its infancy then, the internet was not widely used, and MMORPG's did not exist. Therefore, it's completely understandable that pathalogic gaming does not appear in the DSM-IV, but this needs to be corrected in the DSM-V.
Preparation for publication of the DSM-V has begun, with a target publication date of 2011. Working groups for the various categories of disorders (pathalogic gaming would most likely be categorized as an impulse control disorder, as is pathalogic gambling) are being formed THIS YEAR. You can go to www.dsm5.org and register for an e-mail newsletter which will keep you updated on the process (it's free). Once you've registered, you can also SUGGEST additions to the manual.
There has been some discussion recently on accepting input from affected persons and their families to the DSM-V. Here is some info on that, and note that this guy has an e-mail address, so consider sending him an e-mail on the subject too. http://psychservices.psychiatryonline.org/cgi/content/full/55/2/133 (scroll down for full article or download full-text pdf)
This is something concrete that you can do to further the cause of progress in this area. You can register and suggest even if you are not a professional (there's an "other" category when you register), but if you know or have contact with any psychiatric professionals that work in this area, send them an e-mail with the link to www.dsm5.org and ask them to weigh in NOW. The more input we get from folks in the psychiatric fields, the more weight this campaign will carry.

The daisy, by the shadow that it casts,
Protects the lingering dewdrop from the sun." -------William Wordsworth
