Gosh, I never noticed this! They do, just checked. That has to be one of the reasons why I was recommended time ago to distribute the gatherers among different berries, one ends extracting more food this way. I can't find something I proposed time ago: I wouldn't make the berry tree disappear when done, but leave an empty bush that can provide a little wood. Either one chops them for wood, or leaves them for food. Now I'd add that one could then make regeneration a bit different: not slow and continuous, but faster and at certain times, depending on the tree type.

When you are singing up for the lobby in 0ad, doesn't it only let 1 person per hour on the same ip sign up? Why not do that for the forum also 

We are in the Delenda Est section  (for now ).   By this I guess you mean how they would look when promoting? That would be great, I think I mentioned to @Emacz long ago that their armour shouldn't be changed in the promotion system, instead some other extra equipment should change, like crests, cloaks, greaves… while the armour being left connected to their corresponding techs (it's not nice that both things are so disjointed in vanilla). Of course it would be more realistic if techs unlock unit variants instead of just changing stats, but as @LeJardindEpicure says, it would change quite some things. I'm not against that, it's just a different approach, but what I proposed falls in the middle of both worlds: you already have the units, just a bit more differentiated according to armour "weight", and each has corresponding techs that change their armour (stats and looks). If, in some particular cases, some tech allows for the production of something quite different, then a new unit could be unlocked (I'm going to mention something about this regarding siege machines in my post of the Athenians, since I ran hard into this problem some time ago).
