Slashes in titles of threads

The current configuration of this forum has a problems with titles of threads that contains one or more slashes (or backslashes).

It is directly connected with generation of non-standart thread link.
In most cases slash in URL mean division by subdirectories.

If we click on that link (e.g.: http://masterrussian.net/f39/russian...ack-18133-new/ , it's URL for thread `Russian\English and back.') then web-server is can't find the directory `russian' inside `f39', and even more so it's can't find the directory `english-back-18133-new' inside `russian' (which doesn't exist). And browser shows up 404 error.

Please, don't use back slashes (\) in your thread title to avoid this problem.
The forward slashes should be OK now. They will convert to dashes (-)
