Facebook will probably be your best opportunity for something like this. There are some very active Ecuador expats there… and more than a few wanna-bes who will give you bad information, so tread carefully. But…there are pages for various cities (i.e. Cotcachi expats) and one for coastal expats, called Ruta del Sol. There are also some Ecuador Expat Swap pages now, too — more like online flea markets than anything, but these would all probably be good places to post once you get yourself established.
If and when our schedules coincide, I’d be interested in this myself.., so please keep in touch.
By the way, some of the posters on some of these Facebook sites as well as on other forums out there are… eccentric. And some are very critical and love to tear into others. Not sure why that is, but do be aware that you have to be careful of some of the egos….
