Hi,
my create group button on the groups page is placed in the headline div instead of the main #buddypress div, i like it to be.
Code looks like this:

<div class="post-headline">
<h2>
<a title="Permanent Link to Groups Create a Group" rel="bookmark" href=""> … </a>
<a class="button bp-title-button" href="http://www.mtgeco.net/groups/create/"> … </a>
</h2>
</div>

I dont know where to edit buddypress or maybe my theme (atahualpa) to get my create-group-button to the main buddypress div.

with hopeful regards,
Wil
