Folks have indicated that they are having issues with some of the links not opening due to the owners site thinking of a pass through situation.
I have been advised to ensure that you have your browser setup up to open links in a new 'tab' or 'window'.
This should eliminate the issue. If have tried this and still have the issue with most of the links, I would like to be contacted at firstname.lastname@example.org
, we can setup up a test forum for you to see what we can do in the application used to post this forum.
