Hello Joyce,
You would need a Pro account to use the edit features (copy, paste, format, etc). as described in FAQs 1 & 2.
You can add your blog postings in various ways. Normally this would mean adding individual blogs as separate stories within one particular eBook.
We have identified certain issues with Empower blogs which we hope to address shortly. This includes problems experienced with avatar images. In the meantime, if you are able to change your avatar image to non-floating via your blog control panel, this might convert simply by entering the URL address without the need to cut & paste.
I hope this information helps.
Best regards, Paul.
