Send a note with your real name, your trail name, the town you call home and your email address to email@example.com. I will send a Blogger invitation to you that, if you answer within three days, allows you to post in the normal manner.
You will be required to register at Blogger.com first. This establishes a "dashboard" for you listing all the blogs you create or with which you are affiliated. Each blog on the dashboard has a button that allows you to craft a new post.
Links are similar. Highlight a word you want to become a link, then click on the little icon shaped like a chain, type or paste in the URL. The link word now becomes blue. You can do this to link to a Flickr gallery, for instance.
Note that while all letterboxers are welcome at the table, this blog is primarily for those of use who ply our hobby in Mid Missouri. But if another cluster wants to set up a blog, let me know and I will help. The other administrator who has the same ability to add folks and delete untoward posts is Lnd-Crzr.
