I greatly appreciate the added sections in the forums. But I also agree that the preview text is unnecessary.
1) Put a larger font size for the text, because it is very small and difficult to read
2) instead of the preview put: "last post by XX", but this is not necessary
3) I also agree the adds on the top are a disturbing element. Like Ausdorrent said, they would be better to the side or at the bottom.
4) I have an idea for the genres sections. The browse by genre is a great thing, but it is only for the current season, right? I think it would be a nice idea to set up a search engine for the archives as well, so that when people look for an older anime in a specific genre, they can find it. We get a lot of new members asking for a good harem/ecchi series or a romance series. They know the current season, but want to watch more and are looking for older series. I think that would be a nice feature.
One more idea what to do with the white spot on the right side, where the preview text is right now: maybe we could add some cute anime character, that is doing an inviting gesture or something like that. You kill two flies with one hit that way!!!
we could use one of these Haruhi pictures, it would complement the Mikuru image we have on FTV as well:
What do you think?
