Hello,
I am interested to work on this plugin. The important thing here is where will we take correspondence between IP and country. There are some free services, but they dont have latest IPs in database and sometime can flow. Another way is to buy iptolocation database, but this will be charged annually. Please let me know what option would you prefer.
You can message me here, or skуpe 'grabthemail', or email [login to view URL] to discuss details.
Thank you.
