Hi, I work for a user-generated business how-to site called Work.com and one of our members, a marketing consultant who runs tours in Second Life, just published our first guide to doing business in Second Life: http://www.work.com/doing-business-in-second-life-1285/.
But we need more! We'd love guides to making money in Second Life through building, scripting, retail, running nightclubs, stripping, real estate, and anything else. Also, guides on how businesses can successfully market themselves within Second Life while adding to the community...
We'd love to see you write your own how-to guide on Second Life: http://members.work.com/CreateGuideSplash.do.
