As I've been working on my site, I've so far come upon two things that I've been trying to figure out how to integrate into my site. I've been able to adapt some existing plugins but so far have no luck with other things.
1. I have one need that's related to privacy. I'm converting my regular WP install to wpmu/bp. I have imported all my users across because I don't want them to have to register again but the flip side of this is that in case some users used their full names or email addresses to register, I feel uncomfortable having them in the members directory by default. I wondered if you could think of any ways to "hide" members or have them opt in to show up in the members directory to begin with. I have almost 1300 members and really don't want to lose them. I downloaded Jeff Sayre's privacy plugin but that's only for profile data and your wires. That doesn't do anything to hide or remove yourself from the members directory.
2. For your magazine theme, one thing that I've been having to do is to adapt the category post plugin to show thumbnails. We used to use themes like thestars, and themorningafter, which have featured categories on the front page without widgets. Cosmic Buddy has the widget areas, I just needed to find something to plugin there. Long story short, one plugin that I've found that's incredible is Justin Tadlock's plugin "Get The Image." This plugin will pull from either attached images, url's in the content, a default image, or a custom field and will resize and crop the image for you. The problem that I have with it is that when it creates the thumbs, it only changed how it's displayed. It doesn't actually create a thumbnail sized image to display. If you attach a 5mp image to your post, on your home page, it will load a 5mp image, but in an 80x80 size. I tried to adapt it and use timthumb for image caching and to do the resizing however GetTheImage actually creates the URL and full content for the image so you can't parse that into a script to call timthumb to display it. I thought I'd let you know about these plugins and ideas for your magazine themes that you have in development or see if you have any ideas for these situation.
Thanks again!
