I'm mostly on ADPList as a mentor, but recently I tried to find a mentor for myself and have had such a terrible time, even with the "available soon" feature because there were folks who had upcoming availability, but just don't respond to the session requests - so all six sessions I requested were autodeclined after a few days.

Incorporating a 'Start time' filter, akin to the one used in Airbnb Experiences, would offer a superior solution.
