As far as I understand it, Mudchat has not been used that much because of stability problems. Things may have changed now there does seem to be a genuine huge improvement at Mudcat but over the past years, other more reliable systems have been used in preference by some.

At one point, I provided "folkchat" which I am informed was used until people (I'm told Mudcatters, not "outsiders") found ways of abusing the free (it was fast and stable but security/admin control was non existant) thing I'd set up by kicking other users and playing games with multiple identities. Giok provided a solution that is used by some from there.
