OK, let me clarify some things:
the additional field to select a date was a last minute addition just before cpg1.3 came out - I added it, because the old date field contained a real bug: it simply didn't work. As we were in the last stage before the release, we had already gotten back all language files from the translators, it was impossible to internationalize it. As the banning page will be only visible for the admin I think it's only a minor issue if a tooltip is in english for the moment. This will be all internationalized in cpg1.4
I agree with Casper: do not shout "bug" if you only discover cosmetical issues that depend on personal taste in the future, this is similar to shouting "liar" or "thief" all the time - it upsets developers...
CPG1.2.1 introduced banning, and the admin was able to ban any IP address. This resulted in a couple of support requests of "not-so-experienced" wannabe admins who accidentally banned themselves. Users who can't tell their own IP address from another user's IP address should in fact not touch the banning feature at all - those who are even silly enough to change a vaild IP address that already exists in the database to their own shouldn't touch banning either. To get rid of those support requests were unexperienced users banned themselves I decided to add the "is-admin-IP-address" check, and I think it works fine, since the number of support requests of people who banned themselves has dropped.
There has been a discussion on IP banning in the past, I won't repeat it in detail, just giving some facts: most users don't have static IP addresses, but get one assigned from their ISP once they log in, so their IP will differ each time they visit a webpage: banning doesn't make sense at all for those users, as they will be able to log in later with another IP address. Instead, someone else who will be assigned the banned IP address from the pool of the ISP will not be able to visit your site, although has hasn't done anything wrong. Another drawback of IP banning is the fact that users behind a proxy (e.g. in a company) might appear to all have the same IP address publicly visible - if you ban one of them, you'll ban all.
The banning of non-routable IP addresses has been discussed on the devel board before, and we decided to make this admin settable if the admin wants to be able to ban non-routables, e.g. if coppermine runs on a LAN. The admin switch will be in cpg1.4 - if you need it urgently, just remove the checking routine from cpg1.3.x
I appreciate your language file contribution and your willingness to help coppermine mature, but it would be even more helpfull if you could provide real code, themes, support etc. instead of fighting bugs that are merely cosmetical issues (if at all).
