Does anyone know what this means that I need a 3+ reputation to post more then 3 posts in 120 seconds?

Specifically:

"ERROR
As a new user, you can only post once every 120 second(s) until you have earned 3 reputation - please wait before posting again"

Its an antispam measure to keep bots from spamming the boards. I'm pretty sure the reputation in this case refers to getting upvoted at least 3 times.

@Khahan That makes sense, thanks!
