Cave Story Tribute Site Forums

Via User Settings, but you have to attain 250 content posts and be a registered member for...10 months, is it? Well if you don't worry so much about post count, you'll usually pass the minimum registered time.

Ooh, I see. Alright.

I think you only have to have 250 posts.
I wasn't a member for that long and I still could change it.

I remember one of the older users mentioning a minimum registered time. Perhaps it's not as long as I think it is.
