New module Registration Question
Small communities may want to defend themselves against spam robots. It can be done easily, if there is some common trivial knowledge everybody in your community is aware of. You could ask questions like "What is the ending of phrase 'we are from Tallinn, we will...'?" Every Estonian can answer the question, I bet you cannot. This is especially useful for languages other than English, you could ask a question like "What is the sum of two and seventeen (answer with words)?" If some of questions are tough ones, you can have many of these.
This is just a rework of Registration code module. Works for me on 6.5. No warranties of any kind.
If you are interested in converting Registration Code module from 5.x to 6.x, you can use this module as a reference and compare the differences.
You can download the module from http://tyshalom.ee/mattias/regquestion.tar.bz2 where it will be available for a limited time.
Also, I am not aware how the new module proposal is done and have no time for it. If anyone finds it useful, please use or commit it.

Use defence in layers
There are several takes on the use of CAPTCHA in the security section of the modules list.
To block known bots from even getting to the sites content let alone the registration form have a look at http:BL.
To help defend against spam from bots that got through other defences as well as human spammers you might want to try Mollom and similar modules.
Regarding contributing a new module have a look at Helping with development under Contribute.
