Ideally, when users click on a link posted on a topic, the link should open in a new window and the following message would appear right before the redirect:

"We are taking you to the requested link... You are now leaving xxxx.com".

Perhaps it could be included as an optional setting in future IPB releases, just like in the Links System mod....

+REP, very good idea!

and if it's enabled, and the Remove 'Thanks....' redirect pages? is enabled or disabled, the link redirection page should always show.
