I have a few suggestions to make the Ultimate Linux Newbie Guide's forum(s) more user friendly.
1. Display new or changed threads in bold text for each user so (s)he will not needlessly re-visit threads. You may need to use cookies to implement this suggestion.
2. Add an editing function so a user can correct or remove any erroneous information (s)he has posted.
3. Add a 'Report this post' function so a user can report any Spam or abusive post (s)he comes across, thus allowing a forum moderator to review the reported post, and take what ever action is deemed appropriate.
These will do for starters. If any one else has any additional suggestions or comments on my suggestions, please chime in :).


an icon with a folder and a star against it if the forum contains new posts or updates, so each forum is highligted when new content is there.
Thanks for your comments. I'm not sure the CMS forums will allow this feature (1), but you may notice I have put the most recently updated forum posts in a feed on the right hand side nagigation of every page (Active Forum Topics). You can click straight onto that to find out what has been said in any given forum topic.
With regards to forum point 2, there is a preview feature available to users before posting an item which I would recommend you use to edit any errors before submission, I'll check into any options that allow you to edit forum posts after saving them.
I'm not sure that the CMS allows a 'report this post' feature, but it may be available via a third party add on. I'll check it out.
Thanks again for your suggestions.
Regards,
Ali
