Show others that players are on free trial and can't communicate

As much as I'd like to see some of the free trial restrictions lifted or eased, I don't see that happening any time soon.

But what I would like to see is that it's made obvious to anyone else around me that I'm on the free trial and that I can't send tells or join FCs. I hate feeling like an antisocial jerk and that I'm ignoring people who are trying to be friendly to me, but the reality is I simply have no way to respond to them. :(

This was a problem when I originally made the free trial account a few years ago, and now with the extended trial it's even more confusing to those around me.

Just a reminder:
Free Trial Players cannot use the "shout", "yell" or "tell" in-game chat options during the Free Trial.
Free Trial Players cannot create or join a Free Company during the Free Trial.

SE could do something similar like they did with Returning Players and make a little icon for Free Trial players that shows up next to your character's name. Just so others know that you're on the free trial, for anyone who doesn't want to seem like they're being antisocial when their communication options are limited like that. A good suggestion that should be easy enough to implement, I would think.

Auto reply could also work. We already get the "player couldn't receive a tell because he's in a different world" message when people are in duties. Similar system message for "player is not unable to answer to the tall due trial limitations" or some such would be enough of a hint to seek the conversation in /say.
