Set up Questions – Can I…?

Hi friends,

I’m smart enough to be here, but not smart enough to really understand some of what is going on. I have a separate website that I would like to roll into my network. I want to re-design the website using the network set-up. I love the theme, the plugins, etc. and my other website was built awhile back using

I’d like to keep the domain name, though, from my separate website instead of having it be a subdirectory of the main site of my network.

Another situation. I have a client who would like a little website built, and it makes sense to me to use the structure I already have with my network. However, the client wants to have their own domain name, not my network name. Does this make sense?

Can I use this plugin to accomplish these tasks?

Thank you in advance,
