Permission for a second account?

[loramin]

Make a post in this forum. Choose the prefix "IP Address", and then politely ask for an "IP Exemption".

Also, as it says in a sticky in that forum:

When posting for this, please include the account names of every person that will be playing from the same IP, as well as the identities (real first names) / relations to those players, and please make sure that at least one character has been created under each account. Please verify the spelling of each account you specify. This format works best: Real first name - Relationship - Loginserver Account Name
If you fail to provide us the format we have requested it will delay your request.
If you have requested an IP Exemption in the past please provide those accounts too.

Once you request the exemption you just have to wait. The staff does them in batches, so if you're lucky you could get it tomorrow, or you might have to wait a month, or maybe even longer.
