Your browser may not support TinyMCE. You can see the TinyMCE compatibility chart here. As you can see the following browsers support TinyMCE: Internet Exploret, Firefox, Mozilla, and Safari. I, myself, am using the Opera browser which does not support TinyMCE.*  Thus, when I post content, I use the Firefox browser. *(However, Opera is the fastest browser I've used so far, and I encourage you to try it. It also comes with a ready RSS tool, which is very useful when you want to subscribe to specific content. When using Opera, just click a particular XML graphic of WriteLit.com, and you will get automatic RSS feed from this site).
