Staff John senpai is the most active and dependable staff in this forum, you see.
But I have a feeling that Staff Ethan will also steal my heart if he keeps up his good work. 
John is the best
Didn’t just changed my name but complimented my cat s2 haha
PS: now i don’t look like an idiot who put his full name as an username xD
I know tis already waaaaay to late for a reply, but it may be useful for others who have the same issue.
As you already know, tis possible to change the forum name by contacting a Staff member. However, the truth is, we can freely change our usernames during a 24h period after registering to the forums for the first time, and before iCBT2, that time would be something around a week or so. The Edit option will be there, but once the period expires tis gone.
Back when I got myself here, I too fell for the trap of using, lets say, the wrong method, so I had my gmail name being displayed, so like every normal girl, I panicked. I did some research and finally found about contacting a Staff member could solve my problem and thankfully, Staff_Shawn did it.
Now if youre still wondering why they removed/limited the feature, twas something to do with the possibility of broken links, threads, posts or name citations, as the influx of new players was insane (I recall seeing the counter displaying 149,000+ in the final day of iCBT2 registration window; could be more).
I hope this can help others in the future and if this information is in any way wrong, Id like to know, since tis based in my experience with what happened, and Id gladly change it if needed.
It’s good to know that there is that other option too thank you.
I will contact someone soon, tbh for me is not really a big deal the name as it is actually, it is my IRL nickname anyway (My name is Fernando so it just take off the FER part and leave the NANDO, pretty simple lol) but i might change to my gamer nickname later on.
The staff is really kind and will be happy to help you and take like 2 days to respond
(cc @STAFF_John )
Just some words of thanks for @STAFF_John who changed my forum name (YAY).
Thanks for the trouble to find time for my request.
PS: I asked this morning (around 10AM) and got it changed around 1 hour later.
Anytime. 
And yeah, figured your name could be Fernando. One of my brazilians cousins is also called as (Fer)Nando. lol Btw, gratz on your name change.
Ah ha, yeah generally my family call me Nando, and a few friends, but most decide to call me Fer LOL, but it sound so feminine, i don’t mind but its weird when i hear it lol.
I have no doubts, as I have the impression it sounds a bit like fair or fleur. lol
Hahahahaha, well i didn’t thought that far but you are right, i was thinking more like confusing with Fernanda, which is the same as mine but for females.
Just don’t go changing your icon too or I’ll lose track of you!
Hahahahaha, i was thinking on changing it tbh, just don’t know what to put there, maybe i change for another spore or something else.
I confess i thought he was a new member when i saw the new image haha
Hahahahahahahaha.
@Sixaxis freaked out on other topic:
At the end of his post lol and there some more stuff after.
YOU CHANGED IT HOW DARE YOU
But also,bonus points for Shokugeki no Soma.I am so hype for season 2 this summer.
Hahahahaha, yeah, but i hate the part where everytime i watch or read a chapter i get freaking hungry LMAO.
Thank you! Now I know I can pass on this one. lol
Hahahahahaha, you mean on Shokugeki? Don’t do that, it is freaking awesome, much better than Addicted to Curry imo, AtC is on a slow pace right now which make it very boring.
NO, I wont watch that. Theres things stronger than me, and thats include food. (I got almost a stone watching Umaru-chan (all that junk food >~<) back at the time.)
Hahahahahaha, i had a hard time with Yumeiro Patissiere with all that desserts and cakes and what not.
