Got an Internship as an IM - Need a few steps to guide me along the way

Hello warriors!

I've been lurking for some time trying to learn the ropes of IM. After browsing a few threads I noticed you guys really know your stuff. Like many others I feel this is a great place to seek advice.

I will start by telling you a bit about myself. I am a university graduate with a B.Comm streaming in Marketing Management. I have recently obtained an internship where I will be in charge of the social media / e-marketing side of the business in North America. The B2B company (service provider) mainly sells webinars to large companies.

I have no existing experience in this field other than what I've learned in school. I hope to use this job as a stepping stone for bigger opportunities.

I can pretty much do the basics such as : setting up a Facebook page/group, opening a Twitter account, create a presence on LinkedIn, and showcase the service on a YouTube channel. But I would like to know more advanced techniques I can use to create awareness for this company. Are there any good tools for those social media sites I've listed?

My main concern is that on the Job Description/Responsibilities they require someone who is able to "drive attendance and registration" to these webinars. I feel because this is a B2B venture, social media marketing wont be as effective.

I like to consider myself fairly tech-savvy. I am a quick learner when it comes to using programs or applications.

I would like to thank everyone in advanced for taking the time to read my thread and helping me, and maybe one day I will return the favor by contributing something of value to these forums.

- Let me know if you guys need any questions answered
