There's a great place in Finland called Haku.net (Seek.net in English), which is also a link indexer like Links. It allows webmasters to receive the information if their links in their in-box with a very easy way: You just fill in a form, which asks for your email and the information is sent to the input email. Would this be possible with Links 1.1 or could it be installed to the upcoming Links 2?
The "Haku.net" also allows its users to seek information in a quity interesting way. The address of the indexer is "http://haku.net". When a user writes, for example "http://haku.net/Alex", in his browsers location, the script will automatically search the keyword "Alex" from its database. This would be quite cool with Links too, wouldn't it? =)
