I'm sure Vicky is right... she knows all about this stuff!

Just wanted to say that I had a few such minor offences, but when I ran my criminal record online to see what was there, nothing came up since they were all 7 years old or more (but I had never been convicted of anything, they were just arrests, one where I was found not guilty and one (a misdemeanor possession of marijuana offence as well) that I did six months probation for under deferred adjudication, so it would only show up as an arrest, rather than a conviction. But that was in 2000, and it seemed to have dropped from my records by now.
I only wrote down a speeding ticket I had received a few months before applying. Not sure if that was the correct thing to do, though.
It's probably safest just to mail in the sheet, since as Vicky says, none of those would cause refusal anyway.
Good luck!!
