I think not having an inbox limit would be amazing as long as outdated pms can be removed one way or another. ^.^

Put another way, when you send a message or post in a roleplay, you know the other participants received it. Nobody gets to ignore it. No plausible deniability at RPGuild because we're serious business.

Looking at the other side of the coin though, what if someone keeps on spamming your inbox, knowing fully well you received all their messages? In that case the option of ignoring somebody may be quite useful.
