It took me some time to gather the information I needed for a certain problem, and so I thought that I would post that here.
To be more specific: the information pertains to editing Warcraft 3 maps.
Seems to me like would be rather too specific for here, but the What topics can I ask here? indicates otherwise.
I'm not asking whether I should post my Q–and–A: I'll do that and judge by the reception.
I am asking for a new warcraft3 tag; if someone thinks that none should be made, then please explain for posterity.
