<p>There are two options for sponsorship, and any amount is appreciated.</p>
<p>For the features most in demand, use the ChipIn widgets.  To sponsor these items simply click the buttons below.  For details, see <a href=http://www.dave-cohen.com/node/3033>my earlier post regarding planned features and goals</a>.</p>
<p>The second option is to <a href="<?php print url('node/add/dff-sponsor')?>">pledge sponsorship</a><?php if (!user_access('create sponsorship')) print " (login required)";?>.  Use this feature to target a specific item in <a href=http://drupal.org/project/issues/fb?states=all>the issue queue</a>, or in return for help on a specific site.  The pledge form will prompt you for details, then give you payment options.  For sums of $500 or more, your logo can appear on our sponsors page (coming soon).</p>
<p>The <a href=http://drupal.org/project/fb>Drupal for Facebook</a> project is primarily a volunteer effort.  Your contributions make ongoing development possible.  Please consider sponsoring.  On behalf of myself and all the project's users, thanks.</p>
