Mark Heintzelman's Blog

A blog is a series of personal articles recorded in date-order somewhat like diary entries. You can use your blog to keep track of your collecting adventures, your purchases, your thoughts and ideas, anything that you think other mindat.org members would be interested to read about. Other members can leave comments after your blog entry, but you can delete any comments you find inappropriate.

Mark Heintzelman's Articles

Articles are pages created by you to share with other mindat.org users. These may be serious (a formal scientific article) or personal (you could write an article about your collecting adventures, or about your artistic creations). You can work on your articles in private until you are ready to publish them. The best articles will be promoted throughout the site.

Unlike Blog Entries, you can continue to edit your articles if they have been published (should you find new information, for example).
