Okay, I think it's less that Negima isn't well known (it was [i]the[/i] most popular manga in the west at one point, so that's not exactly plausible), and more that... It just kind of seems like you haven't put much thought into it. An interest check is supposed to be just that, a gauge for interest, so you should probably work things out a bit more than "I like this manga, let's make an RP out of it!". As much as I like Negima (at least until the Magical World arc, that kind of dragged), I just... Don't really see much interest in the incredibly barebones setup you've provided. I'm intending this to be constructive criticism but I'm kind of bad at that so I hope it comes across the way I intended, but yeah. Constantly bumping the thread isn't going to do it; you're going to have to put a bit more work into your OP. I mean you don't need much, just a basic explanation of what it's all about and what kind of setting and tone should be expected, along with maybe a bit of flavour text to make it seem a bit more lively.

If you work on it a bit and try again, then maybe you might get some interest. Hope things go well for you next time, at least.
