Theme Sites. These are of course thematic, which will be helpful on what theme you want to use in a page. Scrapbooking is like Wordpress. If you are making a website powered by Wordpress, you will look for nice themes that you can work on instead creating your own. It should be appropriate in the long run as you post and update it. In scrapbooking, templates will stick for a long time after some time of adding all the elements, and it will be the basis of the overall look that you can't change. Photo Sharing Sites. These sites are both theme and group sites at the same time. Photo sharing is mostly their goal, but I have seen scrappers post their layouts or projects. So you will get templates or their ideas as well.
Because newsletter templates are available in all variety of lengths and sizes, there is really no limit to the content that you could potentially write. Keep in mind, however, that you should probably keep down your word count to a level that people are comfortable reading. While you may think everything that you are spouting off is fascinating, it's helpful to first sit down and make an outline of what you want your main message to be, or what the major news is that you are trying to share.
