I've read the tripcode and saw the board. But I still dont get it. Can someone explain Dx

"Tripcodes can be used to uniquely identify yourself", meaning if someone has your name, it'll show that you're another person than the other dude.

Now, to make a tripcode, put an exclamation mark after your name. Then, put in a password, like if this was a regular forum.

Example: Sato!coolguy

And then, it'll generate a tripcode into Sato!w2131, to us. I hope that makes sense. And the test board is for you to test out different passwords to make different tripcodes.

Hello! I am new! Nice to meet you guys!

i think i got it. Now then, is there any way to do the same for chat

Chat and the forum are separate entities, so no.
