Let me start my problem from the begining:
I have a forum like yours (SMF 1.1.5) but it's problem was that google spiders did'nt crawl it's topics for more than 1 year and my search friendly urls is not functioning because of apache issues, so I download a mod called pretty uls which rewrite all my forum urls to make it readable by just removing the ID sessions and let it appear as a normal url, then after I did that I tried to generate simtemap with your script but still my newly rewrited pages is still ignored?!
I want to understand where the problem is? & If I left the forum without submitting a sitemap to a google webmaster tool, is it guaranteed that google spider will crawl all my forum pages next time noting that my all non-forum pages + my first SMF home page is already indexed by google.
Thanks in advance & am waiting your replies.
