Hi, welcome. From your spelling I can see you're not from the US like most people here. I'm from Australia, we have other members from Britain, so there is still inside knowledge available, with reference to your health system and education system.
The privacy thing - you also need to keep it in mind when crafting your sig. It's really important TO YOU to keep your identity confidential (and hence your kids'). That way you can vent all you want here, about whoever and whatever, and the person or system you're venting about can't track you and use your words against you.
For example - you may mention this site to a friend, or a teacher of your child may find the site all by themselves (after all, they deal with problem kids too). Can you imagine them surfing here, and seeing a familiar face? And if they read on further, and you just happen to be venting about your son's teacher, for example...
You may think you won't need to worry about that, but trust me the time will come when you will be glad of anonymity here. If at any time you feel the need to divulge more personal stuff about you it can always be done with a PM (private message) or in some other subtle way.
Once you've got the settings just how you like them and you're comfortable with the acronyms, you will find this to be a welcoming, warm, informative group.
