Currently, selecting the service 'Twitter' changes the social media account forms so that the 'Account name' field becomes the key field on the form, rather than the URL, which appears to be the default for all other services. Many services, such as WhatsApp and WeChat work on account names (or phone numbers) and the account name field used for Twitter would be far more appropriate.

Please update the 'Social media services' add and edit forms so that there is an option to change the 'type' to account name, rather than URL, on a per service basis. Please also take this option in to account on the constituent social media account add and edit forms, and display the correct field on the constituents social media accounts data list.
