Been playing with the settings of this Blogger setup. Didn't realize that I had setup this account since November 2008 but just didn't get around to using it. I don't recall trying it it before. I guess I might have been trying out the different Google account products and have accidentally enabled it.
From the current experiments and searches, it appears that I can put up multiple blogs under a single account. Am thinking if I can move the other websites that I'm maintaining under a single account. However, those sites contain a lot of pictures and it seems that pictures are counted again my Picasa quota. The free account comes with a 1GB limit. I should remember to resize my pictures and upload them somewhere else. The other option is to pay for the additional space. If I can monetize the contents from all those sites, $5/year for 20GB of space doesn't sound too expensive.
I will need to have the design of the website moved though and this will take extra time.
