Limit of 1 link in signature
 

1. Is it possible to limit the amount of links that appear in a users signature?

2. Also is there an easy way to add new pages that are not assigned to specific sections (Like if you want to add a privacy policy, terms of use, etc..)?

1) Not by default. You will need a custom mod for that. Check the mod section if such a mod already exists. if it doesn't then you cn request it at the paid/unpaid request forums.

2) Yes, there is a guide about this at the article section. There are also several mods that do that. One of which is coded by me.

Do you have the links to the instructions?
What is the link to your mod?

Here you go.
