Aliasing hanamura_yosuke to hanamura_yousuke.

Reason: Or backwards. Regardless, the former is how the name is spelled in the English version.

Aliasing dojima_ryotaro to doujima_ryotaro.
Aliasing dojima_nanako to doujima_nanako.

Reason: Same deal.

Aliasing teddie to kuma_(persona_4).

Reason: Eng->JP. Or maybe Teddie_(persona_4) if it's too generic.

Use [[]] in the OP, please.

I've confirmed the long vowels in the names, but I think someone fixed these already. I added the aliases anyways (also, it's doujima_ryoutarou, so I included that).

And as 0x said, please include the [[]] around tags for wiki links, it just saves me a little bit of time, that's all.

Edit: looks like you edited them in, thanks.

As for teddie, isn't that a type of clothing too, or is it spelled differently?

teddy, I think. It only has one post though, the other two being mistagged posts which should be teddy bear.
