Ryoukai is showing that you understand and accept something (or acknowledge it).
Police officers or members of Self-Defense Force tend to use “Ryoukai” very often. (in a sense of “Roger!”)

Wakatta is just telling that you understand something.

Naruhodo is like “i see.” it’s showing your agreement.

だと思います。

It was awesome talking to you guys in person. It gave me the boost to study even harder.

もう一度有り難うございます。

Abrassart, I notice you use the emoticon at the end of every post… do you mean to come across as stuck up? I don’t see what else constantly rolling your eyes at people can represent…

Also, what about doing a Premium lesson with a photo of the JP101 office? Like a conversation at the JP101 office, as a joke…

The worst T-shirt I ever saw can be bought at the underground floor of Paris’s biggest japanese bookshop. The underground floor sells manga (both in japanese and french) and caters to teenagers, most of whom don’t speak japanese (but will by japanese mangas anyway, because it looks cool… I know, I did the same… ).
There you can by an all-black T-shirt, with a red antique-seal-like text that reads (in hiragana) : “にほんじんになりたい”….

Have you seen the grammar bank in the Premium Learning center? It has definitions for over 280 grammar points, just like this one:

Ppoi is a suffix used in informal spoken Japanese to change a noun into an adjective.It is similar in usage and meaning to the English suffix “y” in the terms “girly” and “filthy”, or “ish” in the term “childish”. Like its English counterpart, ppoi usually has a negative connotation.

Also, it has links to related lessons. These lessons should definitely add more insight. Thanks again!
