Where can I advertise my Kingdom Hearts RPG forum?

That's pretty much everywhere you can go to advertise. I'd advise against joining other forums just to advertise for your own because that's just insulting the moderators of the respective forums.

I guess you could try making a video advertising it on youtube, but don't be totally obnoxious when doing it, like "OMG JOIN MY FORUM IT'S THE BEST!!1!!!!11" That kind of stuff. Don't abuse capitals and exclamation marks because that's a total turn off and just leaves a bad impression.

And January was just 3 months ago. It'll take a while to get a lot of members. RPG forums aren't as popular as those that spread news regarding the series and the like. Just be patient, and the possible members will just come on their own accord.
