I am online at SL now since the beginning of March 2009 and it's funny to see how by even entering this virtual world the power of blood can't be resisted. Yes I write in rl too but with one difference. In rl I make money with it :p And no, English isn't my native language but being in SL is a great way to improve that.
I come and go in SL and will write here only about my experiences in SL.
This picture shows u an example of OMS. OMS is one of the most typical "online" syndromes. It's already developed at the start of entering this world. Those people that feel like struck by lightning and see this world as one big candystore are going to see this world as a playground to accomplish everything they ever wanted in real life and become the first victims of OMS. It's obvious that there is only one cure for it.. leaving this world as soon as possible. If not they will develop a severe form of OPS as this picture shows. The mouth can't be closed anymore and the tongue get's all swollen. It's best that you keep safe distance and inform the local authorities.
