You will need a plugin for that.
I have the search engine friendly url's, id just like to shorten them even more for advertising purposes.
There are two ways to make Google SEO URLs shorter:
1) use a shorter prefix (for example t instead of Thread-)
2) set URL length limit in Google SEO URL settings - subjects that are too long will then be cut off at the end
For an URL like "fw4f3f" you would have to modify the Google SEO code or write your own plugin.
If i could write my own plugin i wouldnt ask for support.
Im not sure you get what i want. For example if you go to tinyurl.com you put in your address and it makes it shorter. I want a script or a plugin that can do this for me.
oh sorry ;
I hopp someone can help you about this
