LSGG tower is gone too some days ago. No more LSGG coverage

.
I wrote to LiveATC, using the ad hoc form, a few months ago to offer them coverage of some LSGG frequencies. I never got a response.
So I wrote to them again a few weeks ago: No reply, no acknowledgement.
I admit I'm a bit disappointed: I offer to contribute to liveATC, and nobody takes the time to answer me...
