bbc bracket?

[xrl2]

I know the bbc codes are in brackets []....is there any way to modify the brackets into curley brackets? {}?

long story short, i'm integrating smf and joomla.

Unfortunately i don't know how to get the "allvideos" mambot to work on smf. which shows up as {google}video{/google} on the smf stream 3 modification.

the stream 3 modification uses the brackets [google]video[/google].....so basically to make it easy, if it's even possible, how do you change it from brackets to curley brackets?
