[/\/\@/\/ |_|]

Most projects have either mailing lists (like GRUB) or bug trackers (most SF-based projects, for example). Start by finding a bug you want corrected, fixing it and submitting a patch to the right place. Remember to read all the rules and requisites beforehand: most projects have a defined coding style, others require you to perform a copyright attribution, etc. Also, whether we want it or not, politics and hierarchy is also involved here, usually for the better: be bold and assertive, but don't disrespect The Elders of a big, mature project - remember GRUB is not Wikipedia and they could decide to reject your patch, either on technical or philosophical reasons. Well, I think that was all. Good bug-hunting! :KS
