Hi Steve, Correct me if I am wrong, but there are a lot more things you can check for with regEx, for example;
- If it has a @ sign and only one - If the first part of the email has more than X characters, and less than X characters - If the first part of the email contains only letters, numbers, underscore or hyphen etc. - If the second part of the email more than X characters, and less than X characters - If the second part of the email contains only letters, numbers, underscore or hyphen etc. - If the second part of the email contains at least one dot and no more than one Etc. Etc. there are many more things you can check for, since I have not found any concrete and accurate info of what an email can consist of I am a bit stuck..
