Changing thread tag separator from commas to semicolon?

[Alfa1]

Commas separate tags when entering those. But my site covers topics that have commas in there. How could I make it possible to allow thread tags with commas in them?

Preferably I'd like to change the separator to a semicolon. ;

I believe the comma is added here:
.commalist li:after {
content:",";
}
If you only want to change it for the showthread.php page, then you probably want to use an id when changing it like:
#tag_list_cell .commalist li:after {
content:",";
}
and do that for other areas you want to change it.

For changing the separation as commas, I think you'd have to edit at least the function fetch_rendered_tag_list and rebuild_content_tags and possibly other functions also. Do a search in your files for "taglist" and see what comes up.
