To make the username no longer than 30 characters use this: `/^[A-Za-z][-.\w]{1,29}$/` [download] This will match when the first character is `[A-Za-z]` and is followed by 1 to 29 characters of form `[-.\w]` (thus making the total length of username from 2 to 30 characters) And yes, `\w` caters for `[a-zA-Z0-9_]`	[reply] [d/l] [select]

if single character usernames are allowed, `{1,29}` should be replaced by `{0,29}` ~Particle accelerates	[reply] [d/l] [select]

\w stands for a-z, A-Z, 0-9 and the underscore (_) os it answers your question. about your second question, of course you can limit the string's length, for example if a username length should be maximum 30 characters long than this will qualify: `/^[A-Za-z][-.\w]{29}$/` [download] the first char is mandetory to be alphabetic and the 29 in braces replaces the '+' sign to note exact number of chars.
