I finally tracked down the thread on http://osdir.com/ml/web.server.yaws.general/2005-11/msg00023.html, and back track on sourceforge archive - they've moved the link to http://sourceforge.net/mailarchive/forum.php?thread_name=20051123073142.GB24712%40delora.autosys.us&forum_name=erlyaws-list .

Hi all -

I found that Im.yaws can help with dynamically reloading of modules from the thread http://sourceforge.net/mailarchive/message.php?msg_id=c22844d10610011618x3513f847ye4357bfe050108a9%40mail.gmail.com, but I was unable to get to the its link http://sourceforge.net/mailarchive/forum.php?thread_id=9044541&forum_id=12456 (I received an error saying permission denied, please contact administrator). 

Are there something I need to do to gain access?
