Easiest way to create new accounts is to use the "My Accounts" screen,
http://www.eqsl.cc/qslcard/MyAccounts.cfm Don't forget, if you are using the same callsign for the new accounts the date range cannot overlap.
If you sign your QSOs with the call "ac4m/p", you should create an account for ac4m/p and upload your logs for that operation to that account. Incoming eQSLs need to be addressed to ac4m/p for the QSOs to be confirmed.
