Request any desired string you'd like, whether you'd like it to be case sensitive or not, whether 1337 is allowed or not, and whether you'd like it to be private or public -if you end up choosing private, please provide a suitable method of contact-
Please do remember that the difficulty of generating a tripcode depends on its length and number of possible variations.
