Edit: Ignore the following paragraph, T@H is back online, working again :D
---------------------------
There are lots of errors appearing on the T@H main server:
http://server.tah.openstreetmap.org/
It'd be really nice if this were to be fixed.

Other news:
I went for a challenging survey cycle around Montmorency,
osm.org/?mlat=-37.723945&mlon=145.133812&zoom=16
I couldn't use Potlatch, because there's too many trees.
Nor can I drive by car, because there's too many dead ends.
There are many many walk ways, parks, and playgrounds scattered around there, all on a big hill.
