Amy,
Things like how to open a Twitter account are not covered in this course since this course is focused on developing a strategy. However, it is quite easy to open any social media account you want. Twiter, just like all other platforms, walks you through registering a new account when you simply visit the site. Part of developing a strategy does require you to first become familiar with the tools so you gain a better understanding of the culture of the communities behind the tools. Don't forget, these aren't just tools, there are people behind these tools so we are truly talking about online communities with cultures, social group behaviors, values, etc. that shape how one interacts on different platforms. You'll be happy to know that learning tools is the easy part and is the least important part which is why this course doesn't walk participants through each tool. Strategy is the challenging part as many struggle with developing purpose behind their usage. You'll find that different departments have different goals. It is likely Admissions uses Social Media to generate leads. That wouldn't necessarily be the same as your objective so think about how you can collaborate while still being able to focus on your primary objectives in the Career Services office. Make sure you download the guide I made and posted in the Lounge that is designed to be a handout to help you start educating students on how they can leverage social media - it will provide you with a long list of recommended thought leaders to follow on Twitter in different topics: http://lwire.us/?l=63C9.
