No. A convention. :-) > (i.e. can I celebrate my bug-finding yet?) Depends. If it's a _desired_ convention (because people regularly have problems with e-mail addresses and just don't care for upper and lower case), it's a good default setting. In _your_ case, it does not apply, because it introduces problems. So if you intend to make a local modification, that's no problem because you _can_ configure such things. This is the power that comes by the freedom of choice. You can celebrate this. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
