Form Not Posting

[DoLeeDa]

I'm was relatively sure I was doing this properly, however it appears I am not so here I am. I'm setting up a gaming guild website and attempting to get a form (created in a "page") to auto post into my recruitment forum. When I hit my submit button everything is processing like it works correctly and taking me back to my main index, however when I check my recruitment forum it isn't showing any new posts.

Here is the link to my site:

www.timfwow.com

Here's the code I'm using:

<form name="input" action="http://www.timfwow.com/index.php?forums/recruiting.3/create-thread" method="get">
Username: <input type="text" name="user">
<input type="submit" value="Submit">
</form>

I have also tried:

<form name="input" action="http://www.timfwow.com/index.php?forums/recruiting.3/" method="get">
Username: <input type="text" name="user">
<input type="submit" value="Submit">
</form>

So there it is, what am I doing wrong?
