Help Wanted - Website Review

I am seeking a small help to review one of the website:
kicdonline[dot]com

Any feedback and suggestion for website redesign ideas are most welcome.

Thank you all in advance.

1. When creating an account, the notice that the account was created and an email was sent appears 3/4 of the way down the page. It's easy to miss. It looks like I'm just forwarded back to the homepage without any notification.

2. When I log in from the Login dropdown, there's no notification that it was successful. If I hover of "Login", I see that it worked, though.

3. If I register with a username of "Jo<1>hn", it's silently reset to just "John". I understand you're probably trying to prevent HTML insertion, but wouldn't it be better to just fail the account creation instead of having a silent change?

4. The link to "3 Dots" in the designed by tag at the bottom of the page does not work.

Design, layout, functionality all look good. Clean site. Easy to use. I didn't have any trouble navigating around. Good job.
