HOW TO ENSURE CLICKABLE MEGA LINKS
Sometimes when you post a Mega link with special characters in it, due to the way it's parsed into the post the link that is then displayed becomes broken/unclickable, and others then need to copy & paste the whole URL line into their browser address bar manually to make it work.
There is an easy way for posters to make sure their links stay clickable:
When you are posting (in the reply mode) you click the Insert Hyperlink icon and two url boxes appear - see attachment "a" below
You then paste the complete Mega link (include the file key) between the two boxes - see attachment "b" below
