Yes of course
It's not as easy for everybody as it seems to be for you, though. It's better if I add convenience tools to make it easier, like maybe a tool to take a pasted URL and turn it into a link, or an IMG tag generator. What I'd really like to do is a WYSIWYG message editor, and there's a good chance it'll be in the next software release. Medium-priority=good odds. That'll be nice.
