In most discussion forum software, when you follow a link within a message, the link will open in a new tab within your browser and not leave the message / thread that you linked from.
This form software leaves the form and goes to the link. If you don’t drill down too far at the new link you can just select the back button and return to the this forum and thread.
Just a suggestion. Consider changing the forum software (if possible) to open the followed link in a new tab or window rather than leaving the forum altogether.
Thank you for the consideration.
