Can I use my account on another country portal?
Your account belongs to the portal you registered on, and your dashboard shows that portal.
An account is created against the portal you registered on, and that portal is what your dashboard shows: your listings, your enquiries and your favourites are the ones belonging to that marketplace.
Browsing is unaffected. Every portal in the network is open to anyone from anywhere, with no account and no regional restriction, so you can search another country freely and send an enquiry there — remembering that sending one while signed out creates an account on that portal for your email address.
If you advertise property in more than one country, do not open a second account with a different email address to do it. Use the same address and talk to us, so the accounts stay connected and your billing and enquiries do not split in two. Distributing one listing to several portals is a feed question — see XML & feed sync.
