I was hoping to create a second account for a new character who would be an A.C.M.E. agent; unfortunately the forum won't let me create an account since one is already linked to my email. I recall reading a post which said you could have multiple accounts tied to one email so could someone pleas tell me what I am doing wrong or if things have changed.

Could be a glitch, try signing up with just any email address and then I'll link it to your existing email.  Message me when you've created this new character -- Thanks.
