Congratulations on successfully registering for this group blog. Feel free to play around with this by posting random messages and commenting on one another's posts. Let me know if there any major problems. You can upload images with the square blue icon to the right of the toolbar and adding hyperlinks can be done by highlighting the text in question and hitting the green icon on the toolbar.
I am the only one designated as administrator which means you are pretty much limited to positng and commenting.
