Hi Hank!
Like most have already mentioned, it's going to be very difficult to get WGT, to interveine unless you can pretty much prove that the owner is either passed, or in some other way incapacited. I'd suggest that you first try and contact the owner if you have not otherwise done so and then if that fails try and appeal to wgt for assistance, but know this is probably a long shot at best.
It's a shame this happens so often to clubs, especially one with 100 members such as yours, left hanging. Once you do get things sorted out either in your present club, or in some other, I'd recommend that the owner who ever he/she might be, make sure to provide a means for the transfer of their club in advance, by giving his/her login info to a most trusted friend. This is also a tricky point as well, as wgt advises that you never ever share your ID/PW with anyone, but until sometime in the future they might see fit to add a second or assistant owner capability, little is likely to change.
I've also taken the step in my club, to post a letter of intend in our forum page, stating that I've willed the club in a certain order of suscession, should I become inactive after a given period of time. Again, not sure exactly how that might play out, but at least, it does show wgt a clear intent, just incase something should happend to me and I'd suggst that every club owner do the same for their members!
Good luck and best wishes in your effort to revive the club you are in and keep us in mind, we are always seeking active and serious members into our family.
