Allow uploading of .swf

I recently made a really cool .swf banner for my forums but didn't realise until after I tried to upload it that I can't use it, just comes up as an [x] on the forums.

I think that it'd be a good idea to allow uploads of that file type.

(If anyone knows a site that gives HTML code from uploading a .swf, please tell me )

Thank you.

Added:

I found a site that gives HTML codes for .swf but it only gives a thumbnail sort of thing.

There is a way to have flash Logos/NavBars

Just look in the tricks & Tips section

Thanks
