Friends, this is different than the forums. One person only needs ONE blog. They can come back to it and keep adding to it forever. You don''t need to start a new blog, every time you have something to add, you just need to make a new blog entry.
But, I'm not the boss here, and maybe there is reason for some to need two or more blogs. Just be aware of the difference because if everyone starts a new blog every time they want to add content, it's going to get unmanageable fast. Now, no further from me on that.
