That's a really bad idea. Users can bring the whole site down with
malformed content if you do it like that.
At least you should do something like that:
try:
usercontent = render_to_string('whatever.html', {...})
except TemplateSynatxError: # maybe other exceptions?
usercontent = ''
render_to_response('main.html', {
'usercontent': usercontent,
})
