I would like to suggest a
[sms]-bbcode which generates clickable links to compose a new SMS.
And it would be perfect if there is also support for the &body-parameter, to provide the user a pre-filled SMS message. With that feature you could generate pre-filled premium-SMS for example. Would be great if it'll be implemented

Alternatively this feature could also be provided as this:
<richtext href=sms:+87888&body=KEYWORD>Click here</richtext> ... today it isn't feasible because the
jsessionid is also be transferred to the bodytext of the message.
