2 Quick Questions

(1) How can I use HTML (ie to make a link clickable) in a message?

(2) Is there a way to keep the system from posting a new message in the overview section every time a change is made to a already published message?

Thanks

1) PP is setup to use textile formatting, which has easier syntax and it more secure against malicious/poor inputs

2) No, not really. Other people have commented about this, so we may look at a possible solution.
