Merging accounts

Could the appropriate person please p.m me or send an email about what needs to be done to merge my accounts. I have my original one linked to registerations but with the same email as this user and can't get my info onto this username and now that i've updated my email on this one with the same as origianl one (thinking that might help) i've made it so that i can't login with older account. it just logs in under this one everytime by default. Thanks for any help
