I'm not sure if this is an issue but I have seen issues in the past where a guild has a great site for sharing ideas and such and members either don't know about it or have no interest. So I thought I'd post some ideas of how to get more activity on these forums.
1. Like most online games there's always set guides for different classes and how to optimize their abilities. Since this game is still technically in open beta there really aren't any good guides out there for specific classes. This forum would be a great place for members to log on and see how some of our higher ranking members play their specific class. This means posting talent specs, what types of weapons they use, attributes which are most important for them, certain skills used most, etc. This would also make a good starting point for new members to learn about their class and how best to use them.
2. Most people enjoy knowing more about the people who are in the guild. Maybe starting a thread for people to introduce themselves and talk about who they are and such. It would bring the guild closer and thus create a stronger guild as a hold.
These are just 2 ideas I have and seen before, feel free to express any responses you want. If forum activity isn't a problem then feel free to disregard this post
