Twitter handle was registered, but had never tweeted and looked abandoned. I contacted a friend who works at Twitter and after a bit of investigation was able to get @learndot as well
Is this something that's easy to do? Can it be done if you don't know anyone inside Twitter? I had to settle for something like @myappnameapp instead of @myappname because the username was already taken but had never been used. I'd be interested to learn what are the Twitter policies regarding this.
I had to do this sans connections, and found their form worked pretty well.
In my case I had a stronger claim - the company I was with (@ShirlawsUK) had registered the handle originally, but handed it over to an ex-staffer who had changed the password, never used it, and left several years prior (so email mailbox was long dead). Took about 48 hours from memory, and the account was ours again.
