i´d always check and bookmark baka-updates.
Baka-Updates Manga - Your Reviews, Series, Scanlator and Latest Manga Release Resource
they list mangas and manhwas, give summaries, release info and info about scanlator groups as well as links to those groups. the best site to check on mangas and manhwas.
the only manhwa i have (so far) is "unbalace x unbalance". i´m a westerner and had to get used to the western reading style of manhwa...man, that´s weird...
