Форуми / Cotonti / Support / Changing separator in URLs.

I would like to know how to change the separator between URLs from "/" to a custom one. 

Be it changing it in every single system file or hopefully being able to create a php function where I can in add in a custom separator be it in the admin panel and then through out the whole system it changes. But that's for me to figure out. 

Ive checked tpl files and for example recentitems.tpl, I've been able to remove the table which is great but the separator "/" is not in that file. So that means its being written from the core system files and I can't seem to find it.

So I hope some one can help me!

Wow I feel stupid. Thank you.
