For finding some bugs on Polkassembly and suggesting fixes

Summary of Post Content:

• The post discusses issues with the current username validation in Polkassembly.
• The current Regex allows usernames with only special characters like "-_-" or "...".
• The author suggests a stronger Regex to improve validation.
• The recommended Regex is ^[A-Za-z0-9]{1}[A-Za-z0-9.-]{2,29}$.
• This new Regex ensures usernames start with a letter or number and are between 3 and 30 characters long.
• It also allows letters, numbers, dots, and hyphens in the username.
