I appreciate everyone's hard work in this so far and I realize this is just the beginning and there is a long way to go, but I figured I'd offer some suggestions as well.

When automatic signatures are allowed in forum posts, in my opinion it clutters everything up and is very distracting to the discussion, especially when images are allowed in the automatic signatures. I suggest a very simple, streamlined forum structure where comment text can be read from top to bottom and all the miscellaneous info (user photo, post time and date, reply button, flag button, up/down button, etc.) are all on the left column of the comment. I also suggest removing the feature where the first few words of the comment are posted in large blue letters at the top, since they are just sentence fragments that do not really add to anything, or possibly provide a blank for the user to enter their own comment heading or leave it blank if desired.

Also, I don't know a whole lot about those live feed tools, but if it's possible and you weren't already planning on this, it'd be great to have a customizable "Live Feed Page" where you can view all of the forum topics and other content you've saved to your live feed page to keep tabs on which ones have new replies, etc.
