Hi, welcome to Grand Theft Wiki! Thanks for your edit to the User:A-1 page.
You should discuss it on Talk:Niko Bellic to try and figure out why people think you're wrong, and to come to an agreement. Maybe you'll need to find evidence (eg a screenshot). If people don't respond, or keep undoing your edit without explaining, then you should speak to them on their talk page. If it's multiple people, or you still don't get a response, ask a member of staff again to intervene. Staff do not know everything (I certainly don't know the answer), but we can help make sure everyone has a fair say in the decision, and people don't revert your edits without a good reason. Hope that helps - Gboyers talk 19:59, March 20, 2010 (UTC)
