You can't use HTML – so please just stick to normal text, and use ordinary carriage returns to break paragraphs. Web pages and email addresses you mention will get magically transformed into links.
If you are spamming the comments with links, be aware that we tag the links in comments so search engines like Google ignore them when ranking pages.
You don't have any universe-granted right to post messages here. If they're junk they'll get deleted.
