So many of us regard the Sphere as an important part of their poetic life - and it doesn't come free. There are regular operating and update costs. Alex does a tremendous job at maintaining the Sphere and providing it to the rest of us as a reliable service - but there's a cost involved - and he's not very comfortable with money raising. So let me ask for him. If you use the Sphere, and can afford it, this would be a good time to donate.
Details here. And thanks.
