Need Shorter URL Links

Need Shorter URL Links

Some time ago, all the site's sound and music was located in a specific "Audio" category and the link to this section was http://opengameart.org/browse/audio. Despite the length, it was possible to share this link on forums.

Now, Music and Sound Effects have their own categories. And I think that's great. However, the links to each is very long:

Sound Effects:

http://opengameart.org/art-search-advanced?keys=&field_art_type_tid[]=12

Music:

http://opengameart.org/art-search-advanced?keys=&field_art_type_tid[]=13

My real issue is not the length, per se. Rather, I find it impossible to share these links on other forums where I tend to participate. Specifically, these forums use a recent version of SMF. Simple Machines Forum software is quite popular - probably the most widely used.

I can enclose the above links with [url= (address) ] [/url] BBCode tags. However, the link itself does not work. That's because the [] brackets between field_art_type_tid and 12 or 13 is intercepted. I can only assume such brackets are prematurely interpreted as the end of the link.

Is there any way to make links to the 8 categories under Browse more resemble the short, simple links in Collections? If nothing else, can the [] brackets be removed or replaced with something else?

I suppose someone could create Collections of each Category. However, as people add new content, such collections would become outdated - unless there was some way to update them automatically.
