Hi all

I am trying to validate username using validator rules

For my username, the requirements are

First character should be a-z,A-Z
Remaining characters can be a-z,A-Z,0-9,_

i want regular expression to include in the mask

I tried giving ^[a-zA-z]\d{1}[a-zA-Z0-9_]\d{2,25}

its not working,

Hope anyone correct me

Thanks in advance
