Apparently the links don't work in Signatures on phpBB unless you alter the code via the Admin panel. I imagine they wrote the code this way so that spammers couldn't add links to their signatures.

They should be working already at the Table. You can use a link with the [url] tag or without it. When using the [url] tag make sure you don't have any extra spaces between the brackets or the "=" and the text inside the tag.

Just replace the apostrophe with ' and it will work:
