They arent taking any equity but the companies will use mailchimp which is a paid service. So either way, Mailchimp will probably get something out of it.
An extension is something we defiantly wanted to do from the beginning. That was one issue we saw was either people not wanting to go to seekier or simply when they search they don't go back to seekier. Thanks for the feedback!
When you say a more consistent setup, I hope you are not referring to the fact tables are used, because changing the theme for a certain user is MUCH easier to do in css. Okay since you mentioned includes, your obviously a lower end developer. Have you ever heard of OOP or MVC? But I guess if it works, why question it.
The site's UI is way to boring. Even if its suppose to be simple. Also being a programmer in my own right, I was looking at the source and using tables with spacers? I mean come on, its 2010.. Also another thing I am noticing is, is every bit of your application all in one directory? I am seeing files like indexg.php, gamesg.php. I may be wrong but that might make it really hard to pick up any more developers or investors who are a little tech savvy. Just my 2 cents. Good luck though.
