RMI - Remove Method Invocation

One thing I should point out is that EJBs are a Bad Idea (tm) unless you are 
in a truly distributed and loosely coupled environment.  For example, check 
this post:

EJBs are a great idea when they are used as designed.  Because of the 
overhead of RMI, using them as 'business logic' wrappers in a non-distributed 
environment could cause problems.  For example:

Finally, a Gartner study (no link handy) claims that 70% of folks building 
J2EE apps do not need EJBs.

SOAP is a way to invoke messages on a remote server.  AFAIK, SOAP _is_ the 
IDL...

Any mutt users out there?

I just started using mutt a few days ago. Man, it is so nice to be
free of the click, wait, click, wait, click, wait routine! I do
have one quick question: is there a simple way to 'Mark all messages
read'? Or to perform an arbitrary action on all tagged messages?

I looked through the online help, but couldn't find anything that
seemed pertinent.

Thanks for any tips.
