Scripts for anime/manga community sites

Hi, these days I happen to chat a lot via PMs in few anime sites and, because of this, I need to constantly check them. The RSS function is helping A LOT for the forum topics, but the PMs are really a pain.

So, I would like to request scripts for sites like anidb, myanimelist, anime-planet, anilist.co. Would ask for hummingbird too, but the pm system there seems like it is not enabled yet.
Thanks a lot in advance ;)
