Can't get past "You have made seven posts as..."

[rando1000]

I have an NPC avatar and I'm trying to make a post, but I get:

You have made seven posts as "ZeldaNPC". You can change your avatar name until you have posted 10 messages to the messageboards.
Click here to change your avatar name.

If you do not wish to change your avatar name, you can ignore this message.

Unfortunately, I CAN'T ignore the message, because hitting submit post just brings me back to the same message. Essentially, I can't post with this avatar anymore.

My guess is that you are attempting to submit a post that is identical to another post on the same page. Paizo has an antispam measure that allows identical posts to preview but not submit.

You're probably submitting another "Flaming Musket Attack: 1d20 + 6 ⇒ (19) + 6 = 25
Musket Damage: 1d12 + 1 ⇒ (5) + 1 = 6
Flaming Damage: 1d6 ⇒ 4"

If you just change one character in the post or add a sentence of description, it will submit just fine.
