A couple other forums I'm on someone will start a general thread just for this purpose - 'show us your cars" or "Love those trees" etc

I reckon if you started a not-for-critique thread along those lines (eg, "Post your favourite Debrovnik pics here") you'll get a good response ( unless of course nobody else has been there)
it also then doesn't matter then if your shot is not perfect - nobody has to cc it.
