Feature Request: Using a custom url

[Zeitgesit]

Would it be possible to change/edit the url to the forum? I have a shorter version as mine sits in an iframe.

So as an example my url's are like this:
https://www.website.eu/forum.php?t=94
instead of:
https://www.website.eu/forum/viewtopic.php?t=94t=94

Thank you
