You can't FORCE others to vote for your material. it only makes them want to vote less. And you obviously have no means of stopping them.

um, sorry about not setting up a demo site. I jsut can't seem to find a free perl supporting webserver that remains up for more then about 2 months.

Anyway, if you want a webserver, I have a version of my webserver on PSC in the vb section. that runs perl.

Enjoy it! and vote for it!

Your perl code uses vbCr, vbLf and vbTab as constants. You probably looked over it in the conversion. Perl needs \r, \n and \t of course..

As I said I have uploded to the server, and I have changed the data.txt file and I have included a keyword "Coffe".

When I tried to search for a coffe, it doesnt show anything related to the coffe.

you can check that by following the link:
