I liked the BOP summary, but have a question (problem) about it. I've gotten web pages to display without any problem, but there have been issues with other people seeing them. I realize that it is not supported in all SL viewers, but noted this sentence near the bottom of the summary: "Other people will probably see the web page also, but if not, they need to check their media settings." Where are the media settings in the standard SL browser?

For example- if you go to the marketplace and search the "Home and Gardren" category for the phrase "TYPE C", you will see listings from many different vendors and different types of articles with this designation. I have seen type designations all the way to TYPE O and sometimes the designation has a number in it like TYPE B2. Some things also have a version designation like "ver. 2.0"

I've been doing some furniture shopping and have noticed that many beds, chairs and tables have TYPE designations and some things have version designations. I have spent the past hour searching for what this means without success. Can someone please point me in the right direction? Thanks in advance!
