Hi Barbara -
Your site virtualassistantsvc is nice, but it's a little plain. In fact, it looks just like one of mine. (Lol, I know it's just the basic WP theme.) I don't know where you are on filling it in, but I recommend you put in some security plug-ins right away, in case you get called away to do something else. (Don't ask me how I know about that

)
The site before that looks very nice, I think. I rather like the font, but I can see where it might not seem quite as professional as some other, more basic ones. It wouldn't discourage me from hiring you if I needed VA services, though. Also, some people for whom English is not a first language might find a more basic font easier to read. As a VA, you may find a considerable market in working with people who are conducting business in English but who don't have a lot of confidence in their own command of the language. As you work your way through the internet marketing world, you'll see many instances of people who probably could have used a VA to help refine their materials before final release.
Another thing - there are a number of premium themes in the membership area. Some are pretty easy to use, some aren't.
As for the plugin issue: I am absolutely addicted! In fact, I have to allow a certain amount of time each day just to play around with WP and plugins, or I'll end up going down a Wordpress rabbit hole. Not the worst thing, I know, but it sure is easy to lose a lot of time that way. It keeps me out of the shoe stores!
