It should be this:
%SUBJECT='%SETPATTREGEXP="^(\[MkForum\]\s)?(.*)"%REGEXPBLINDMATCH="%subj"%SUBPATT="2"'
or this:
%SUBJECT='Re:
%SETPATTREGEXP="^(\[MkForum\]\s)?(.*)"%REGEXPBLINDMATCH="%subj"%SUBPATT="2"'
Ai> What "" are this for? Parenthesis is that what they're called?
No, quotes. They are used to delimit text parameters.

Okay:
%SUBJECT=
Change the message "Subject" header to something new.
'
Begin the string that contains the new subject text.
Re:
Start with the constant "Re: " since it is a reply.
%SETPATTREGEXP=
Next follows a "regular expression pattern".
"
Begin the pattern.
^
The pattern starts at the beginning of the string...
(
...and start with a sub-pattern (or "string" in this instance).
\[
The string we want starts with a '[', but since that has a special
meaning in the world of RegEx (begin character class definition) we
have to put a '\' in front of it to say "A real '['".
MkForum\]
Plain text "MkForum" and of course the closing \], explanation as
above.
\s
Match a single space.
)?
End of the first sub-pattern (which may or may not be present).
(.*)
Define second sub-pattern which is the rest of the input.
"
End the whole pattern.
%REGEXPBLINDMATCH="%subj"
Apply that regular expression to the string held in the current
Subject text.
%SUBPATT="2"
Retrieve the second sub-pattern matched.
'
End the subject redefinition.
