Improper HTML

Hi,

I am not sure if this was the right forum to post this in, but it seemed like it fit to me.

I really love Drupal and try and get more familiar with it everyday. Although I am having some problems with allowing HTML is forum posts, blogs, and new pages.

The problem is this; if you don't have an ending tag to your HTML, then it applies to the rest of the page.

For example, if I made 'this text' bold, and forgot to put the ending tag, '' at the end of it, the rest of this post would be bold.

That goes for the rest of the HTML tags. I don't have a problem adding ending tags (I am used to it.), but some of my members who are not familiar with HTML forget to put ending tags. This messes up everything below their post and effects the whole page in general.

Is there anyway that this can fixed? A HTML ending tag checker?

Is anyone else having this problem with their users?

Thanks for you time!
