Help Removing Lumber Requirement For Upgrades

Is there anyway to remove the lumber requirements for upgrades? If it involves editing .slk files or the .mpq how would I do that and will other players have to have the modified .slk and/or .mpq files to have the modifications?

Yes it requires file editing and importing and such. My recommendation is just make trained units for upgrades then when the units are trained set the upgrade level.

I'm not sure what your saying I should do? Could you clarify?

What files would I have to edit and would other users need to have the edited files for the map to work properly for them?

As of the latest patch the editing of txts has been greatly stripped down, so I'd say you're stuck.

Basically make a unit that costs only gold, and when he is trained at say the blacksmith it will instantly remove the unit and set your research level to 1 or something.
