You may not be aware but the FamilySearch Research Wiki contains information about genealogical societies and family organizations. For example, if you do a search on the word "society" not only do you get a list of societies by geographical area, but you can also find pages created by individual societies and family organizations. There are literally thousands of societies listed on the Research Wiki.
You can find an organization or society in your geographical area or even a surname group with your surname. If you belong to a society or organization, such as a family organization, you are encouraged to set up a Wiki page about your organization and link it to your website, if you have one. If you do not have a website, the Wiki can be a place to put your organization or group online. Bear in mind that the Research Wiki is not a place to post personal or family histories. You might want to look at a few society pages for examples. If you find that your society or organization is listed in the Wiki but there is no page, then you or someone from your society or organization can certainly add the page into the Wiki.
If you are looking for information about genealogical societies and organizations, as the Wiki grows, it will become (and already is) the go-to place for this type of information.
