[Mediawiki-l] Special:Vote and other stuff

[Birger]

Hello there,

After installing the vote extension (copied all the files of
http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/Vote/#dirlist
to the extensions directory, referred to it in localsettings.php and
created the vote-table), i get an error:
"Fatal error: Call to undefined function: isspecial() in
/www/wiki/extensions/Voting/Vote.php on line 46".

I think this error is due to the fact that i am using Mediawiki
version 1.6. Who knows where i can find more info about this
"isspecial"-function and how this can be fixed in version 1.6 (without
upgrading)?

thanks in advance!
Birger
