Okay Jessie, here's what I think is happening.
Creating a trip report is a two-step process. First you create the overall information for the report, or the Summary information, things like your name, the year of the trip, check-marking the countries you visited, a brief description, etc.
The second step, is to create the actual pages that tell us about your trip, the detailed article.
Here's what may be happening, if you create that summary information without creating at least one detailed page, the system loses the report. So if you create the summary page, walk away from the system and come back a few hours later (forcing a time out), or if you create the summary information, and then close the system without creating a detailed page, the system does not save any of the summary information and you have to start again.
So here's my suggestion, create a new report, with the summary information, and then add the first page - even if you just put garbage on it, (e.g., this is the first page of my trip report). Save the first page. When the system asks you if you want to add additional pages, say "no." When it asks you if you want to release your report for publishing, say "no." As long as you've created that first page though and saved it, you should be able to log into the trip report system, click on "my trip reports" and access your report, in draft mode, and add pages to it for as long as you want.
Now, another thing I can't stress enough, type your report first on your own computer, using whatever word processing software you have available (e.g., Word or even an e-mail editor). Save it on your computer, spell, grammar check, and then cut and paste it into the editor. I say this because if you don't do it, and you lose your Internet connection while typing your report into the Trip Report system, you will lose all your work.
Let me know if you have any other questions/concerns.
