I'm not certain if they started the Pre-STO today, because UVS was indicating he would be participating, but we have not heard anything from him indicating that he purchased tokens today! Maybe he will chime in later to give us an update, because he was following things very closely related to the event!
I do know that the webinar is scheduled for 9/27 (Thursday), and I found it odd that it would be after the start of the Pre-STO, unless it actually hasn't started yet! Maybe Cyber C will visit this evening and can enlighten us as to the actual schedule/timing of events!
