With the upcoming changes, I was wondering if it will be necessary to get new addresses and memo codes, or can we continue to use the ones we already have?
I've been using Blocktrades for over a year now, but my transactions stopped being recorded in my profile over a year ago. Is this because I didn't login first before requesting addresses and memo codes?
If you login to your account and go to the "Profile" page, you can then click on the "Mappings" menu option to see all the deposit addresses connected to your account. If you send to any of those, you should get a record of the transaction. It's possible you are using some deposit addresses that you got when you weren't logged into your account (these won't show up).
