1.  put a link on the star in the top left of each post in a thread to link directly to that specific post.
for example, this url http://www.renderosity.com/mod/forumpro/showthread.php?message_id=3590549&ebot_calc_page#message_3590549
links directly to a specific post down the page in a thread.
so when I want to point a friend to a post or even bookmark that specific post, I can save that url instead of going to the top of that page.
phpbb has this feature.

1. place a payment link on the order page to pay by paypal if it hasn't already been paid.  Currently, if you miss your opportunity to pay by paypal during checkout, you can't do it later without involving manual process (ie do a paypal "send payment" to payments@renderosity.com then notify store@renderosity.com who will then manually activate the downloads.)
   here's the info on instant payment notifications http://www.paypal.com/ipn
   many online stores have this feature.

thanks. :)

Good ideas, I'll add it to the list :)

Thanks!
