I uploaded two trails, stuck in a POI in one, altered their names etc and saved them. Coming back to the SityTrail site to look at them after a couple of hours, they were no longer there, although trails saved earlier were still visible! Couldn't find them (there doesn't seem to be a way of getting a simple textual list of all the trails one has uploaded) and eventually uploaded them again from my device. This worked, but where did they go? And can one look directly into the server and one's own trails, anyway?
