There is already uiautomation tag on SQA, but it's initially created in .Net GUI testing of third party components post as a tag about Microsoft UI Automation (UIA) accessibility framework.
But later it was used only as a tag for general questions about UI automation. Considering that new tag "ui-automation" should be created for general questions about UI automation.
EDIT: Another question is what should I do to overcome this problem after raising this question on meta?
