The layout could use a little work. The bevel effect, or whatever texture that you applied to the bevel is over used too much, too much for it's own good.
It also needs more content; people join sites mainly not because of the active members, but because of the content; it's what keeps the people coming to your site. At this time, you currently have 5 links on your nav, most of which don't technically count as content.
The site is really lacking in the content area, and the advice, which I give to most sites starting new like yours, to start big on content, not on flashy scripts or mods. When you start getting members, then add the flashy things. What user are shiny scripts/mods/tournaments/whatever when you have no members? That's why you should focus on content before getting members. PEople like seeing a large navigation list (not one with a size 72 font, one with lots of links) and most of which links pertain to your subject, in this case your clan, and runescape, it would be great to have a lot of content. Also, mainly if you don't have the time to write up content (you shouldn't own a site if you don't have enough time, even for content), you can look around for already written guides and contents, ask the owner for permission, and host it on your site.
I'd say, overall, for a new site, it's pretty okay, but if you're planning to go on like this, it's not good for you, or your members. Keep up like this, and you'll have weirdo noobs joining your forums, asking for admin/mod positions, that kind of thing.
One of the easiest way to get content, that i've seen, is through contests, but it might require a bit of money. Buy something expensive, like a runescape server (not sure if runescape works like that, but whatever) and make it worth like, lets say... 4000 points. Make a simple system like this: (you have enough skills to make a user/admin cp like that, I think you have the skills for this)
25/30 points for posting
40 points for topics
140 points for referal
600 points for tutorial/guide/contents
300 points for hosting a banner/text ad on a site (assuming the site has some sort of activity to make ads worthwhile)
With that kind of system up, and a prize that attracts people, your site should be bustling with members. And you can have contests like these every 2 months or so.
