There a couple of ways to find your posts. You can go to you page, and look under "Statistics" and you'll see two options, “Find all posts” or “Find all threads”. Another way is to just left click above your avatar and under your name on this thread, and a menu will come up with the option to "Find more Posts". A third way is to go to "advanced search"
http://www.yorkietalk.com/forums/search.php and put you name in the "Search by User Name". I couldn't find any other posts made today by you, I don't think it's because you're new, you aren't that new anymore. YT is having server problems and it may be YT just had a glitch. Because your post was long, it might have also been caused by a "user time out". Do you have to sign in to YT? This sometimes happens to people who have to sign in, because it signs you out before your post can be completed. You can have your computer “remember you” so this won’t happen. Just check the "remember me" box when you sign in. If you can’t do that, it might work better if you typed you thread on Word and then copy and pasted it to a thread, that way you won't lose it. Sorry this happened, I know it’s frustrating.
