Hi Susan,
iMacros is indeed a wonderful tool, but it’s not necessarily the best solution for every repetitive task.
– Credit Card, Name, Address etc. can be stored and auto-completed / filled by Firefox already. I recommend you use a plugin like this instead:
https://addons.mozilla.org/en-us/firefox/addon/autofill-forms/
– For repetitive emails I highly recommend using Gmail for a number of reasons anyway and you can used the Gmail Canned Responses add-on.
– For WordPress there are over 13K plugins at the moment that can ease almost anything.
Right now, I’m not even sure you need to use iMacros, it might be overkill for some of your tasks. If you have some more complicated tasks, I’d need you to explain them more specifically and I could tell you first; if iMacros is the right solution and second; how to use it.
Thanks, Bryan
