Here is Noobmigo's method from changing http://www.spacetimestudios.com/show...nges!-Must-See!
to Random Thread

1)Copy/Paste Desired Link onto post
2)Add [ U R L =" to the front of the link
3)Add " ] to the end of the link
4)Type desired rename
5)Add [ / u r l ] to the end.

No spaces except for in the rename.

That is all.
