I’m writing this so that I don’t have to guess next time.

1. Go into ‘themes\wordpressembedded\templates’
2. Create a directory called ‘local’
3. Copy theme.tpl into ‘local’, and open up the copy for editing
4. Find the line that has <title>
5. Add a space right after <title>
6. You could optionally put a separator or something else in there (I use a dash, surrounded by spaces, so it looks like ‘Blog Title – Gallery Album Title’)
