Nubee ?? HTML vs Plain text option when filling out online forms

How do I figure out the correct answer for myself/my system, when given this choice in filling out some online forms? Any suggestions for other good computer learning free sites would also be appreciated. Thankyou.

 

What site? Look at this site, when we reply to a thread, we're looking at a set of basic tools like bold, italic, underlined, etc. This is HTML. To be exact, bbcode.

You don't usually need HTML for forms which are personal info.

 

Thanks for responding so quickly, akhilles. The site was my auto insurance company. I was enrolling to pay my bill online. I was finally able to get my agent on the phone. She made a few calls and helped me answer the question. It had to do with my e-mail server preferences. Anyways, thanks again. I can't tell you how much I've learned from reading this forum. Some other forums are so technical and way over my head.
