Since I have seen this question being asked a lot, I’ll answer it here in a friendly reminder way for all of our followers. Any headcanon or message can be sent BOTH via ask (“Titans, Go!”), submit (“Titans, TOGETHER!”), and fanmail (that little letter icon thingy on the top right corner if you are following the blog) options.
The first option has a 500 character limit, and if for any reason your headcanon does not comply to the submission guidelines and can’t therefore be posted, allows us to privately reply to you so you’ll know why your headcanon won’t be posted.
The second option does not have any character limit whatsoever and allows you to link the text sent, but if you don’t have a tumblr blog on your own you’ll need to comfirm an internet mail account before submitting, and it makes it more complicated for us to communicate with you in case the headcanon can’t be posted (or is a private message for us mods to reply).
The third option also has no character limit, allows you to write links, and for us to reply to you privately if needed, but it’s only available to tumblr blogs following the blog.
Other than that there really is no difference to any way of sending your headcanons; you are free to choose and/or do so in any way you want, and unless tumblr messes up it will be sent to us correctly and we will be able to read it and queue it; so you don’t have to worry over “where” to submit. Note this includes both sending headcanons or questions to us mods; any message of any kind can be sent by any means and it won’t make it different in the slightest. Hope this has cleared any confusion :)
As a little side note, Cartoon Network has comfirmed Teen Titans Go! will get a Season 2 AND WE COULDN’T BE HAPPIER, WOOOOO! :D (twitted by DC Comics and Scott Menville). So thanks to everyone who has shown support for the new show and congratulations for the accomplishment, we are as eager to watch the new episodes as we were for the show’s release ^^
Alright, with that said, happy headcanon-ing and submitting, and again thanks all submitters and followers for the support, you are what keeps this blog alive :)
