[Forum] how to insert automatically a url before a link posted by user?

[cloferba]

i want to anonymize links, so, the hosting of the link, doesnt know where the visit comes from.

so, i was thinking to insert a url of a website which redirects to the url after the .com/

i mean:

is any way to insert a url before all links posters by users?:

http://www.anonymizer.com/http://linkonmywebsite.com

so, i want to add http://www.anonymizer.com/ on all links posted on my forums, how can i do that?
