We do a quick check of all new handle requests and if the one you seek is too close to an existing user we will generally ask you to select something less similar. A new user called Randy Peterson would not be approved for example as it may be confused with Randy Petersen. Similarly, Detroit 1K or Detroit_1K would likely not be approved if we already have a Detroit1K registered etc. If any member advises us a new handle appears too similar to an existing one, we will ask the two members to try and amicably work out a solution and advise us of that, before becoming involved.
The short answer is NO. In general the handle you registered with is the one you are known by during your time in this Community. However, if for instance you started two years back as FargoFlyer and are now based in Tampa, we will allow you as a ONE TIME courtesy to change your handle. To do so you must email a FlyerTalk admin with three username options and a valid reason for wanting to change your handle. You will be asked to keep your old username in your title line for a period of time, depending on the amount of posts that you already have. This will ensure that we avoid any confusion in the community and that your reputation is carried over to your new handle. This is strictly a ONE TIME offer to members, so please think carefully before asking!
