That 'default' thing is already in place. I only have it in beta version on my portfolio right now, but it works wonderfully. I visit
http://www.jockstocks.com/market.php and I buy using market2.php.
The only problem with making it a default page is for people who do not have JavaScript enabled. Plus, we are still considering make it a benefit for paid users. It would fall under the $2.00 USD/month subscription option.
But, then again, I am all for giving stuff away from free. And, Orren has voiced concerns with taking things 'away' that have already been given.
So, to answer you question the longest way possible, it will have to wait. Orren and I hope to do some talking this week and get some plans hashed out for the next month. Hopefully ya'll will being to see some much needed changes.
