Yikes! It only works in the preview. I'm going to make this as a Wiki.
I remember doing something similar. I'll try to link BOTH of the posts I made about HTML on the Forums here.
Coding in Replies (Not really HTML, but worth a mention): Coding in replies
Making Custom Text in the Forums: How to make custom icons/commands in comments and posts
doesnt even work in preview

did you even test this?
huh?
Im pretty sure the <form>
is an html tag, not XSS, as its not injecting anything.
Here on the forums, you can do a lot with html, such as
Heading one tag
and i think you can do css too
test
nope :(
xss means adding interactive content on other ppl's website
also known as injecting scripts into the website source code, but with this we're not injecting anything
hello!

From OWASP: "Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted websites."
Since <form
>s aren't malicious (in the way @mr_owlssssnap2) is using them, in this case, I wouldn't describe the tags as being part of an XSS attack.
and also im not injecting anything into the code
