As a rule, I do the following: 1) For BITNET, the userid and node are all uppercased: e.g. GKM$FAID@QUEENS 2) For internet, the DOMAIN portion (as registered) is upper case, node names are lower: e.g. [log in to unmask] or [log in to unmask] 3) For internet, userids may any mix of upper and lower: e.g. [log in to unmask] or [log in to unmask] ** I respect the case as it comes in the message (mail) for signup ** 4) For percent hacks, a double rule applies: e.g. [log in to unmask] and so on, as required. /Geert
