After doing a quick search there's no "how to" for posting links, so i thought i might make on up.
- type what you want the link to appear as, in this case I will be linking
to "FWi home"
- Highlight the words click the "insert link" icon

- Once clicked you will get this pop up,

- In the "link URL" type, or copy/paste the address of the page you want the link to, (I usually change the "Target" to "open link in new window")

- Then it should appear in blue and underlined (it appeared in purple for me because i had clicked it)

There you go that should be all you need.
P.s. Isabel or whoever may do something to this, move it to where it should be if it isn't in the right place
