Simply Life

I absolutely love Blogspirit! It's great! I do have one concern though. I've been using this since about 4 days ago, and my Disk space on Blogspirit shows it's at 4 MB out of 10 MB allowed. Uh oh. Will this be a problem? It sounds like it. If it did that in about 4 days, what would it do in two months? Or longer? I really don't want to have to delete posts. The whole point, to me, about blogging is saving those memories, indefinitely. Does anybody have any information about this subject? I would greatly appreciate any help here! :)
