You must not use the reply number - 1th letter in your post.

Exactly what the title says. For example, reply #2 cannot use the letter "A", reply #3 cannot use "B", and so on. Once we reach the letter "Z", the cycle will restart.
Additional rules:
No workarounds (omitting the letter from the sentence, using the number 4 as an A, using a zero as an O, that kind of stuff). Simple phrases such as "Okay!" are also frowned upon.
The "Last edited by" text, usernames, profile pics, signatures, and personal text do not count. If an emote contains the forbidden letter, you cannot use it to get around that rule.

Now then, let's get started, shall we?

Did you simply do the -1 option so you could confirm the rules without missing letters?

 

[Power Flotzo]

Yes, it makes for a good precaution.

Anyway, writing a sentence without this letter is, surprisingly enough, very simple.

I'm lost.

Take a look at the first post if you're lost, then. Hopefully, the person below won't have trouble circumventing the taboo letter for their post, as it sees the most usage in the English language. Why, just look at how many of them are in this post!

Nah, this isn't a plight at all.

You did the incorrect letter. It was f like in of.

You did the incorrect letter. It was f like in of.

Where the did it say that?

Okay, trust me, the space in between "the" and "did" is much larger, but it won't show or some reason. THAT'S a problem.

 

[Magolor]

See, here, can't use " ". Make sense?

 

[AwdryFan1997]

O , yea , I've done somet ing like t is before. Or, at least, I tried somet ing like t is before.
