We've decided to add a new contact info option to new thread and thread edit page instead of bbcode. Example of how it will look after you edit in your details and someone clicks on button to unlock your contact info. (Live design will probably look a bit different. Thanks to Andeih for mock up design) There will be another button for contact info unlock history which is available to all users. OP and staff can always view history where as other users need to unlock contact info before they can view history. The contact info unlock history page will contain things like filter by month / year, user name, date and time revealed, user join date, and user country flag. Feature should be ready in a week.
