It is hard to keep track of everything! Make a file in your BOOKMARKS WITH "FREE ADS" and keep them all in there. Try and keep as much on your computer as you can. Whenever you set up a new account somewhere and have a password to keep, send yourself an email with it in there and email it to yourself and then store in a new file "ACCOUNTS" in your INBOX.
Two ways to leave a message foranother seller. When you are looking at their store items just click on their store name which is usually in the upper right hand corner of their listing or in the bottom left you can "ask the creator a question" remember to put your shop name and their shop name too as the emails are not automatically "signatured" for now.
Good luck! You will do fine. You are doing something and remember success is 80% about showing up!
