You have 25 MB of upload space. This will not be enough if you are uploading large pdf files, videos, or images. It may be preferable to use an outside service that you can integrate with Longwood Blogs such as Flickr for your photos, YouTube for your videos, or DivShare for your files. This is probably the best practice, because if you ever want to move your blog to another service you will have persistent links to documents and images that you will not have to update to the new blog URL.
