You should have two windows open in your browser, one with your post, and the other with the site you want to link to.
Click your cursor on the address box code to high light it. Use Ctrl + c to copy it.
Go to your message you want the link in and then Ctrl + v to paste it. A full link will be inserted where the cursor is in the post block.
If you want that fancy stuff where the link is "behind" some text in your post, you will have to get some HTML "experts" to help you with the tags for that.
Sorry about missing out on hunting with you in early December before the wind storm. That sure was something to be driving back north and seeing the damage get worse and worse the farther north I went.
