So I tried to find out how many usernames you can make with the limits established here in Roblox, and the numbers I got were HUGE, and it wasn't easy. I had to find out what kind of math problem I have to make and had to talk with my math teacher. Then I had to change that problem based on roblox's other limits. THEN I had to look up what the heck e means in calculators and change my answer based on what I got. And the answer i got was.... drumroll please!

- gasp - 640.056 NONILLION POSSIBLE USERNAMES!

AAAAAAAAAAAAAAAAAAAAHHHHHHHHH!!!!!!!!!!!!

I can only imagine how long the Url of profile pages would be if we even got CLOSE to that number.

At least we won't be running out of usernames any time soon.

An interesting thread.

These calculations intrigue me.

Did you account for the underscore, which can only be used once and can't be used at the beginning or the ending?

I think the max number of characters in a username is 20
And the max type of characters we can use is 26 letters + an underscore

So 27 x 27 x 27 x 27 x 27 27 x 27 x 27 x 27 x 27 27 x 27 x 27 x 27 x 27 27 x 27 x 27 x 27 x 27 = the max number of usernames possible, someone correct me if I messed up

Wait a second, it's not 27, it's 26 because we can have a max of 1 underscore

Ok so 20 characters max, 36 valid characters, and an underscore

So I believe it'd be something along the lines of 36^20*18

This of course does not account for the username blacklist
