The biggest problem that I've noticed with people new to the forum, is that they don't log in when the first enter the site. If you are on another computer somewhere, or all of your internet cache settings (history, etc.) have been purged, then you can't post anything to the site.
In the upper-right-hand part of this web page, near the top of the main white section, you should see something that says something like:

If you don't see the above, you are not logged in, and your posts won't be saved.
There can be other issues as well, but I think that we would need more information pertaining to an instance that it actually happens, to figure it out. Hope this helps.
