You can set the allowed html tags in the Admin Console ... the default "list" is:
u, a, img, i, u, li, ul, font, br, p, b
underline
italics
bold
Bigger font (font tag works!)
Paragraph one of stuff. l kajd f;kajd kjd ;jd ;fkjad kaj fd ;akjd ;kaj ;ad ;akd f;adkj akdj akdj ;akdj ;akjd ;akd akjd ;a d;ad ;a
Paragraph two of stuff. l kajd f;kajd kjd ;jd ;fkjad kaj fd ;akjd ;kaj ;ad ;akd f;adkj akdj akdj ;akdj ;akjd ;akd akjd ;a d;ad ;a
(Looks paragraph tags work just fine too)
So, if you want to allow any other HTML tags to be used, you would need to add them in the Admin Console.
