Greetings Community!
I want to change email input properties so users could enter their phone numbers instead of email. Here is the list of fields users have to fill:

• Phone number
• Name
• Password
• Repeat Password
• this captcha: https://github.com/Gregwar/Captcha
• Submit

Anyone who can do this please contact me through telegram: https://t.me/tomich1203 ill pay for this. Thank you!
