I've identified three issues with the article. In descending order of severity, they are:
Lack of references. No reliable sources have been presented in the article to verify the claims made about the organization. The article should be built upon information about the Society that's published in magazines, journals other than the Society's, and the like.
Notability. There is no strong assertion of the significance or importance of the organization, although I don't feel the article is so lacking that it's a candidate for speedy deletion under criterion A7. One way to meet the notability requirement is via the general notability guideline: if the Society has gotten substantial coverage in secondary sources, it's deemed to be notable.
Conflict of interest. All the information in the article is currently from a source with direct involvement with the society. While nothing precludes a member from editing the article, members and other affiliated parties are strongly encouraged to back all edits up with secondary sources. I'd have no problem removing that tag from the article once independent sources are in place; the article text is not nearly as problematic as other situations where related parties have written articles on subjects.
