What should be done with e-Sword-users.org, and the domains it owns? on the eSword support list poll area at yahoogroups.
Abandon the site means exactly that. All resources and other content on the site will be lost.
Run it as a one person owned and operated website, means that a single individual will run it, paying the bills, updating the software, adding content, as they have the time and money to do so;
Incorporate means incorporating an organization run by the users, for the users, that operates the website and other projects related to the "current" e-Sword-users.org. This organization could be modelled on The Crosswire Bible Society, or The Document Foundation, or something else.
Find an organization to adopt it, means looking for an organization that is willing to pay the bills, provide manpower, and everything else that is required to keep the website, and its projects up and running;
Something else, means just that. Another option that has not been listed. There might, indeed probably are other options that I haven't yet thought of.
