Directory of Special Interest Groups

April 2, 2015     

Compiled by Marty Merado, GNYM SIGs Liaison Officer.       

Note, for GNYM members only, a complete directory with contact information is available via the GNYM Members-Only Area.

Next edition: For the upcoming September 2015 SIGs Directory (to be published in September-October 2015 Mphasis), all changes in SIG blurbs and blurbs for new SIGs must be received by July 26, 2015. Send to Marty Merado, . The text for all blurbs must be 50 words or less. Thank you.

Please inform me of any changes or corrections. If a SIG becomes inactive, any member can volunteer to lead it.

The rules to start a new SIG are simple:

  1. The proposed SIG's activities must be lawful in the political jurisdiction in which its activities will take place.
  2. The proposed SIG cannot be entirely duplicative (of site and activities) of an existing SIG under another name.
  3. The SIG must be open to all interested M's, except for certain SIGs designated confidential.
  4. The name Mensa or the stylized M may not be used in a SIG's title.
  5. SIGs must have at least one Calendar item in Mphasis between semi-annual SIG listings, except for exceptions designated with the symbol "*".
  6. In addition to other forms of contact, every SIG must list a telephone contact number for the SIGs Directory and all Calendar items.
  7. All contact persons listed in all SIG Calendar items must be current members of American Mensa.

If a SIG is a local chapter of a National SIG, then dues may be collected if the national SIG assesses them. While other local SIGs do not have dues as such, all expenses incurred as a result of their activities must be borne entirely by their participants.

To volunteer to be a SIG leader, please call or write me. Be sure to give me your Mensa ID number. SIG leaders and co-leaders must be current members of American Mensa.

Note: Whether you participate in a National or local SIG, you should know the following: SIGs are voluntary associations of members of Mensa, which operate independently of Greater NY Mensa. Their financial activities and liabilities are entirely their own, and not those of Greater NY Mensa. Furthermore, no SIG leader may obligate GNYM in any way.

Just as SIGs' activities and liabilities are their own, so is the responsibility for disciplining SIG members where necessary. SIG leader(s) and/or the SIG membership have full authority to sanction any member of the SIG whom they deem has interfered with effective functioning of the SIG's activities.

Turkey Shoot

More of an event, really.  We get together periodically, sit together and watch terrible films.  We laugh our heads off, like the characters in MST3K.  Feel free to shout out your own putdowns.  If someone else wants to host one, I'd be glad to bring some tapes or discs.
