With a free account you can upload up to 100MB of data every month (that’s around 30 images depending on your camera)or how much post-processing you like to do). If you register for a pro account the limit is removed.
When you open a new account, it enters a queue for review after you've uploaded 5 public photos. That review takes around 3-4 days. Before that, your photos won't appear in public searches, but would show up if you submitted them to the British Building group.
