Alrighty, I just applied to your guild, and then accepted it, then made another and rejected it:
These are the emails I got:
ChopsTest,
DKPSystem.com from Dark Legion is happy to let you know that your application to the guild has been accepted. You can visit our website at
http://legionskeep.dkpsystem.comChopsTest,
Unfortunately, DKPSystem.com from Dark Legion regrets to inform you that your application to Dark Legion has been rejected. Thank you for your interest in the guild
Which are the standard emails. I'm not sure where your applicants are getting the private message thing on your forums from.
