/signed oh yeah!
Such a simple addition and so helpful, this should have been always a part of the template system.
Look here

- they even post these template strings like "AxNR0kcdHCbURvKnngBAGoAA" in their articles, so why not just add a field where it can be pasted while in game? Or just #teamsay your string so someone can copy (...ehm a chat interface update allowing selecting text for copying, please)
Currently if you create a new template file manually, you have to restart the game for it to appear in the Load Template menu. These simple suggested changes would even free some server resources used while a player logs in and enters an area!
