Sorry, the waiting list is indeed down atm :( You can just send one-line support ticket at https://support.bugjail.com/hc/en-us/requests/new and I'll add you manually.

The underlying technology in BugJail and Microsoft TTD is somewhat similar (capturing based), but the functionality build on top of that is very different: Microsoft TTD still looks and works like "normal debugger plus back button", while BugJail is total redesign from scratch and looks nothing like any traditional debugger.
