Don’t hack the core: http://i39.tinypic.com/23wofh1.jpg

In the core function, they’re only separated by spaces because all the links [a href=”whatever”]tag[/a] are on new lines, and the browser treats the new line as a space. If I knew more, I could tell you how to do it with a plugin, but because I don’t I gave an alternate solution.

There are a couple of different cases for output, one being an array, then you could just echo them with whatever delimiter you wanted.

The file you want to look at is ./bb-includes/functions.bb-template.php and the function is bb_get_tag_heat_map around line 3183 (in version 1.0.2 anyway) I think.
