About visitors and traffic - the first day pulled only 19 people to the office but the only advertising i have installed is a free adnet and the L$30/Week search listing. There are many ways to increase traffic but all of them are pretty costly, e.g. the first place in search ranking is determined by the amount set on specific search terms and you can guess how high it will be for words like 'money'. ;) To be exact: the first place for the word 'money' pays L$ 52035/Week at the moment, that's approx. us$ 200/Week, waaaay too expensive for an info site in Second Life. Other ways are giveaways, free L$, offering freebies...
