Yeah I'm still struggling to find a go to place with up to date information. Eorzeapedia(Gamerescape) has some articles with a wealth of information. However take the MNK page for example, it is severely lacking information. It is ostensibly run by the same people who started the FFXI wiki, which was amazing until they decided to go for a cash grab and create a new version and split the community of which updated it. Makes me sad really.

As for Zam, I still have a membership so no ads but people there are always lamenting being assaulted with ads for other MMO's all over the site.
