Apparently, the thanks button is not a standard feature of the software used to run the forum, and it will cost a lot of time and be expensive to add. Right now, they are most concerned about security - hence the update. As far as I know, the thanks button is on our (the Mods) wish list for the future.

I’ve just noticed that the Mods had had a wish that’s been on the top of the list for a while granted!
