Thanks for the couple of replies. Its always good to get feedback from people outside your circle.
To Nehalem:
All I have used is PHP along with jQuery and 'Bootstrap From Twitter'.
I agree the front-page has been going through almost constant changes to find how it can fit with the rest of the site. Another redesign is probably needed.
I never originally intended the URLs to be that ugly

. Thats something in the pipeline that won't be too much work.
Anyways, thanks for the feedback. Any other suggestions, please let me know.
To Hoopycat:
As for the play-button links... I will overhaul that area.
Replying to posts was a concern I was having and you have validated. I might pull it out of the menu and change the menu item somehow.
Supporting OpenID is a good idea. I will make that a priority. Thanks for the tips.
Good to hear it runs quickly. There are a lot of SQL queries on the site, but I created a PHP function that can easily cache select PHP code to a DB.
