It is obvious that some members really do not get this: creating multiple accounts on POTN is something we consider a "PERMANENT BAN OFFENSE".
Multiple accounts means: a person registers more than one member account on POTN forums.
It is said clearly on registration page "PLEASE NOTE: WE HAVE A STRICT POLICY TO BAN PERMANENTLY ALL WHO CREATE MULTIPLE ACCOUNTS.", it can't be missed.
If you need to change your name: do not make another account! Use thread http://photography-on-the.net/forum/showthread.php?t=568625
If you can't connect to POTN: do not make another account! Please wait a while and try again. If a while won't help, use some other net connection like GSM/Wireless. If problem persists on default connection, report possible suspicions of blocked IP to mods via report button when connected via other means.
