It has been confirmed with Wikia Staff that IP users do not get message alerts. Although they are supposed to, this feature has a history of breaking and needing to be fixed. This means that communication with IP users cannot be relied upon to actually reach the intended recipient even if the user has a stable IP addy. (Many IP users, of course, are wholly unreachable because they edit wirelessly or in other environments where their IP addys change rapidly.)
Accordingly, IP users are hereby warned that they may be blocked without warning, and even indefinitely, since Wikia Staff have now confirmed there is no reliable way to communicate with you. Blocking is the only effective protection the wiki has when a pattern of mistaken or even unhelpful edits emerges from an IP editor.
We'd much rather just talk to you about the errors you're making than ban you. Therefore, this wiki strongly urges you to register an account so that you may enjoy the full benefits of membership.
