I've noticed that there are some quirks on the forum in the new IE, also known as Microsoft Edge.
When typing a message and trying to use the bold, italic, font buttons, etc., yields nothing! Emoticons do not even work!
Anyways, my work-around is knowing how to do the basic html coding.
I just wanted to point this out and I am wondering if you know of a fix or something.
(jury is still out on this Windows 10 upgrade)
