Unfortunately, there presently is no button or link in the community forum to click and jump directly to the Windy website. I'm sure you will get a response from Ivo or another windy developer on your posted suggestion because it is a good idea. But it also may be that the NodeBB software used for the forum may not have a way to do it too. Again, the bosses should know that answer.
For the time being, may I suggest you do like I do and have side by side taps open in your browser with Windy.com in one and the forum in the other.
