This has been brought loads of time already, and every time I have agreed that it is deparately needed to improve communications with more than one linkshell. Sure, you can switch between linkshells when standing around or in battle, but if you're navigating other menu's or crafting then you can't contribute to conversation in a linkshell other than the one you are wearing at the time. 'tis very inconvenient.
/l# would be ideal
