Shared Calendar Subscription like Easy Speak

Since EasySpeak seems to allow members to subscribe to its calendar of events, is there a similar feature or equivalent to do the same for FreeToastHost's shared calendar?  This would help members get all the meeting notifications integrated into their personal calendar and avoid missing Toastmasters-related events.

Sorry no. There are many calendar out there that do that we won't be reinventing the wheel
If you use a gmail email for your club archive email address you could use that google calendar as your share calendar.
