I’m not proficient at php but finally figured out I needed to add these bits to front-page.php in my template to create a new column and make the icons show up. Might want to add a tiny bit of instruction for us neophytes.
<th><?php _e('Forum Icons'); ?></th>
<td class="num"><?php forum_icon(); ?></td>
Great plugin, didn’t even realize how useful visual pointers would be to my increasing number of new visitors – the little pics help direct those who don’t seem to be able to read and just post on whichever forum their mouse lands on first.
Also, any idea how to make it work with the Forum Restriction plugin so I’ve got an image instead of an ugly text link?
