This is for my sig and also to make thread listings easier to read and manage.
It won't show all the code, for example:
If you want to make a word bold, like TEST.
It would appear as <b > test</b> (except with no space after the first b) but if you have enhanced editing on, when you highlight the word and click the "B" button, it will just bold it and not show you the code.
Your sig can get really confusing with all that code.
