I see that many people here are posting weblinks, but these are not clickable and have to be copy-pasted.

There is however a handy feature to make a link directly clickable:

this is a clickable link to focusfusion.org

How to?

Simply click the <a> button under the title edit box.
An edit box opens. Enter the actual web URL, (I typed “focusfusion.org”)
A second edit box asks for a description,  (I typed “this is a clickable link to focusfusion.org”)
Agreed, for html analphabets this cryptic <a> button does not look like something that means “insert weblink here”
Rezwan, can the text on those buttons be changed to something more “human-readable”?

To show how the code looks like in your message editor, I put spaces in the [url… , this breaks the parser

[u r l=http://focusfusion.org]this is a clickable link[/u r l]

Another way is to simply type it in. (without spaces in the [url…)

To make bold text, use the <b> button, the <i> for italic text and the <del> is for strikeout text
