Hi everyone,

I'm new here, so I'm trying to figure everything out. I have seen that people are able to post links from youtube, their blogs etc in their comments. But when I'm trying to post my blog's links in the comments I can't. When I'm trying to post something without the link I'm able to do so though. Does anyone have any idea why?

Likely, the system is restricting you from posting links since it's a new account. It gets lifted automatically after a while (or depending on your activity).
The temporary restriction is there to prevent spammers from posting harmful links.
