Howdy Stahshee! I had not seen you post anything on your I need a WDW fix thread,regarding your trip report. Glad to see you here. I was wondering if you are o.k., and it looks like you are, so that is a relief.
Anyway, in answer to your question:
Go to edit signature-- then click on insert link ( it looks like Earth, with a tiny link under it ) http will be in black, ( you can read the http ) delete that, with your delete button on your key board (otherwise, the link will not work properly) Then paste your pre-trip report link, into the space. Then click on OK. It should work fine.
