If i could change anything in Second Life about how it works, it would be to erase all lag and banish the lag monster to the depths of darkness which it came from. I know that this isn't really possible ut it is a nice thoght to have.
If i could change stuff aot how people are in Second Life it wold be to ensure that only adults who really want kids and are prepared for the full responsibility of that are allowed to adopt them. I see too often kids having to move from family to family because they have been adopted by people who mearly want a few token kids to take out and about with them every now and then. That is not what most kids want in SL. Most of us want a real family environment where we casn be nurtured and thrive. I am sure you all have wonderful families now.... but how many families have you been in before you found the right one for you? I know i was in a few before i found my forever family.
I would also make a rule saying if there is a group like 50l friday kids, each creator HAS to make either a unisex item or 1 item for male and 1 item for femal. Boys are poorly catered for in the majority of SL. yes there are those thast cater for them but they are few and far between.
there are several other little things i would like to change abot sl but i am not going to go into them now. The only thing i will add is that i wish everyone wold remeber that behind every SL avatar is a REAL person with REAL feelings!!
