Just some feedback that I think there are parts of the forum hierarchy that may be counterproductive in terms of a new user or prospective buyer of Indigo might interpret them.
Consider for example, a prospective Indigo user going to "Board index » Indigo Help » Supported Hardware » Locks and Lock Controllers" and seeing something about mostly obsolete Morningstar / Insteon locks and wrongly concluding that those are the only supported devices in that category. There's a similar (or maybe worse?) problem with thermostats, where confusingly there is discussion of Insteon devices, but also a single obscure Z-wave thermostat model.
I suggest that entire branch of the forum somehow be marked as being incomplete or no-longer maintained or something to avoid confusing users. At the very least, maybe put a sticky post at the top of those subforums directing people to the "Built-in Automation Technology Hardware Support" page at http://www.indigodomo.com/devices/ or the plugin store page.
