So, as you have noticed, we can change nicknames. There is only one thing which crosses me.

WHY ALL SUITABLE NICKNAMES ARE TAKEN BY INACTIVE USERS?!

Firstly, I'm tired that people are reading "prefix" to my nick incorrectly.
Second and most annoying thing, WHY REN IS SO SHORT AND POPULAR. I don't need any other names anymore. After so many previous usernames, I don't want and need anything else but Ren. I have some other variants of prefixes which can be read more easily (and correctly, lol) than "koji", but they are taken by those inactive users. ARGH.

This describes my feelings perfectly - [link]
