I have 2 problems with the RSS feed of the forum

1. The rss feed of my forums is showing the different URL of topics, not the one originally created and upon clicking redirects to another URL, this way one single post have 3 different URL's

One is the original URL
Second is the RSS URL
Third is where the RSS URL gets redirected

It creates problems in SEO and Sitemap submissions, please share the solution.

Also, the RSS feed is not displaying all the items.

Please suggest which feed should I submit to Google webmaster tools as Sitemap.

Thanks

I installed latest version of Punbb forum on my site but the Table BB Code is not working, it just simply display the whole code in the topic.

Is there any solution to it?

One more thing is it possible to enable HTML editing in the forum topic editor instead of BB Code?
