Has there been a change in formatting for comments on observations on the website?

I used to be able to embed hotlinks to web pages within comments when I wanted to point to another observation, a BugGuide or Moth Photographers’ Group page, or just about any other url. I don’t know the terminology but I was using either mark-up or html format with carots or brackets, such as,
<url=“https://www.inaturalist.org/people/27047”>My Profile Page, or

My Profile Page

but, although the latter format works here on iNatForum, neither format now seems to work properly to embed links in comments on the website.

Is my formatting wrong or outdated? What’s happened?

Related question: What formatting should I use to display a text string such as those above without them being rendered into active links?

the pages in the main iNat site support HTML and Markdown. you appear to be trying to use BBCode, which is not supported on the main site but apparently is supported by Discourse (the platform used by the forum).

BBCode:
[url=https://www.inaturalist.org/people/27047]My Profile Page[/url]

HTML:
<a href="https://www.inaturalist.org/people/27047">My Profile Page</a>

Markdown:
[My Profile Page](https://www.inaturalist.org/people/27047)

the easiest way to encapsulate small snippets of code using Markdown is to encapsulate them in backticks (`).

to encapsulate larger blocks of code, place three backticks on their own lines both above and below your code block.
