This is very strange indeed. Are you typing your blog posts directly into the thoughts.com site? Or are you typing them in another program and then cutting and pasting them here? Are you using a Standard English keyboard or a keyboard with non English characters? If you will please contact us using the bug report form at http://www.thoughts.com/site/contact_form and provide us with as much detail as possible about the process you are going through to make a post we should be able to identify the problem why this is happening with your posts. Thanks for alerting us to this issue. We will work to resolve this as quickly as possible.
I have found that if I put in spaces or use the tab keys, it will do some funny things to my posting on my blogs. You can go back in by clicking on the edit under your blog (after you have signed in) and erase and fix what you see.
