So its up to the user if he will proceed to access the URL or not since we can hovered it before clicking it.
No it doesn't work, either green or blue URLs will be changed to forum's background color. So you can't differentiate the URLs is Bitcointalk URLs or non Bitcointalk URLs.
Anyway thanks for the info.
Also, would it be possible to have a notification before opening links, sort of "are you sure you want to b redirected to..."
This would prevent inadvertently clicking on links, especially when you're on mobile.
I agree with your suggestion, however the cons of this feature is you need to spend more time to click "yes or no" option, some people might doesn't want it. Perhaps, it's can be an optional feature whether the user want to active it or not, I guess.
