Thanks for the welcome. I am sorry you also had a troublesome preschooler but I am honestly glad to hear I am not alone. I think the knee jerk reaction is "well if he is so darn smart, he should be able to figure out how to act like everyone else!". I wish I had pulled him out earlier. Looking back I feel so stupid having said things like "if you don't have a good circle time today, you don't get to play with your anatomy model". I should have known it just wasn't working earlier.
One fear I have about keeping him at home longer is just that I am pretty bad about being "educationally organized" I get restless at home so we tend to go places like the zoo, kids museum, library, etc. but we are way more likely to be watching looney toons or sponge bob than doing anything educational at home. I checked out those on-line programs through the universities. Something like that might work for us until he starts school.
As for finding peers, I am so happy for the suggestions. He really needs playmates. I saw that our local MENSA chapter has a kids' group. Any experience with that organization? What about SENG? We have a parent group facilitator in my area for them.
I could seriously ask a thousand questions. Since he took the test on Thursday and I got that snippet of information, I have been reading so much information. Is there a good book out there on this stuff?
