It's not possible to register more than one account with the same email address, the more problematic bots create tens/hundreds of email addresses which are different, but similar. Many of them follow the formula of oneword_another@example.com, so I've thought about whether we should make it impossible to register with an email address containing an underscore, but as with so many counter-measures I think that might cause trouble for genuine users, so I doubt that would be a good idea.

What about email verification? If too many accounts use the same email, it doesn't allow you to create it

Hi, @Caroby. Welcome, and thanks for your contribution! I wanted to mention that cycling through buildings is already a feature available in the Autociv mod (you can get the latest version with some bugfixes here). In addition, this functionality has been incorporated into the next version of the game, along with hotkeys for constructing buildings and selecting units by class. The only difference compared to your mod is that, when cycling through buildings, the camera doesn't automatically focus on the selected building. To do that, you need to use the Focus Selection hotkey (default: F). On another note, I tried your mod, but it only selects the first building of each type that I constructed. It doesn't let me cycle through the other buildings of the same type.

not anymore, I got my H key working perfectly now hahaha, much better experience.

Hi @Caroby, indeed I feel hotkeys for certain things like the ones you mentioned are needed (and indicated with button tooltips or whatever), I have it written down for my future suggestions. Since there are some I've always used in AoE and StarCraft, I have to constantly remind myself that in 0 A.D. pressing H won't cycle between Civic Centres (nor could I find a key that does this yet).
