With your script, you must replace "Link here" with a valid link, starting with http:// ... ie, https://facebook.com .
If the issue is that you don't want Guests to see any links, I have a far simpler way
Navigate: Admin panel >> General > Categories & forums > Find the specific forum > click on the 'Permissions' button and change the drop down box that is adjacent to 'See links in the messages' > Save. Repeat for each specific forum.
Only what I get to do is: Admin Panel>General > Categories & forums > Find the specific forum>Permissions>uncheck the box "Guest" under the "View and Read".It's only choice to forbid guests to see the links and the specific forum.
I looked and read a lot of topics related to hide links from guests, but nowhere I found a solution for my problem.Please anyone help me about this, if at all possible.
I read on some forums that do not need to post clickable links for the protection of search engines.If this is true in general.Can you tell me your opinion, that I place links in code tags or not?
