I've seen foo.bar@...e.where.com turned into foo_dot_bar_at_some_dot_where_dot_com (which is a bit stupid IMO). foo@bar@...e@...re@com (which is even dumber) foodotbaratsomedotwheredotcom (not only dumb, but also unreadable) foo.bar#some.where.com (which is sort of neat and tidy) foo:bar@...e:where:com (clever harvesting engines break this on account of : being a member of the interpunctuation class) foo dot bar at some dot where dot com (hard to read) foo#dot@...e#where#com (works, sort of) The list goes on... > 2.

The most important thing is to make sure you can whip up a small sed-script or some such to take care of turning it back again if that's ever necessary. -- Andreas Ericsson andreas.ericsson@....se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231
