Inactive accounts are indeed set to be deleted after a certain amount of time.
While I understand your wanting to see registration open more often, it is a matter of users who want accounts needing to be persistent and logging into the forum several times a day when they can. Frequent forum users tend to catch registration open quite a bit (myself included), and even with the new registration set-up, we still have hundreds of new accounts being registered each month. Hundreds of new users are still getting in, and so it isn't a matter of new players not being able to get in to play. They just need to be persistent, and we promise it will pay off.
I'm sorry if our reply isn't quite what you were looking for, but we do appreciate your input, Nicole. Thank you very much. Let us know if you have any further questions or concerns.
Moving this to The Inputbox, as well.
