OK, here’s what I ended up doing…I’m running WP 3.0 RC2 + BuddyPress 1.2.4
1. Install the plugin CMS Press and create a “feedback” custom post type. No extra taxonomies needed. You could also create a post category and just have it create a normal post, or a page (or child page under a parent “feedback” page, but you’d have to add a line to the code). I decided to do a custom post type simply because I’m using my normal posts for something else, and didn’t want my pages admin area littered up with member fb pages.
2. Download THIS file. Edit the values in it (they’re pretty well commented, but you can also find info on what everything does HERE). Upload it to your plugins folder and activate it via your admin panel.
3. Link to it from each user’s profile page. I did it on the Buddypress themename/members/single/member-header.php using the following (I have my custom post type permalinks set to %identifier%/%postname%/ in CMS Press):
<a href="https://www.clothunderground.com/feedback/<?php bp_displayed_user_username() ?>/">Feedback</a>
I’m sure those NOT using BP can easily find the normal WP template tag that spits out the user’s login name, which you can toss into the profile page link to the feedback page.
Hope this gets us at least a little bit closer to the final goal!
