I've had a reply from gi about the username issue. Exactly as I predicted they said they are working on it and hope to eliminate the problem in the next update. No I'm not psychic,just used to the crashing disappointment that is gi support.
Then to add insult to injury they declared that they would mark my case as "solved"! Let's all try that shall we? Today I have "solved" all world problems. No,didn't work for me either! :)
