60 characters seems a tad excessive and is causing my theme to explode in extreme cases. Users with extremely long usernames are causing hell in my forum which pulls the usernames straight from WordPress.
Is there any way of reducing this number (without hacking the code preferably)? I'd like to set it to, say, 20 characters... a value, which to my mind seems rather reasonable.
As I say, I'd rather not hack the hell out of the code ideally, mainly to avoid issues caused by future updates. However, if anyone does know where to find the code that would target this, please do chime in.
Am I missing something obvious?
