[Mailman-Users] Help with a regular expression

[Greg Westin]

I don't know what the I or | or whatever that is does - I assume it  
does the same thing as {0,1}.  But the important difference between the  
rule I use:
	RewriteRule ^/(mailman[/]{0,1}){0,1}$    /mailman/listinfo [L,R]
and the ones you suggested is that mine also redirects requests for /  
to /mailman/listinfo.  You may or may not want that functionality, of  
course.  Again, I don't claim to be an expert in any of this stuff...  
considering your comments, perhaps this would be the best for what I  
want to do:
	RewriteRule ^/(mailman(|/)){0,1}$ /mailman/listinfo [PT]
I don't know if you can use nested parentheses, and I don't know if the  
PT flag is something I'd want, but whatever works...
