A while back it was announced
that the Eudora mail client was going Open Source and being redone from the ground up using technology from Mozilla Thunderbird on the back end. Now the first beta of Eudora 8, called Penelope, has been released
for Mac and Windows. So if you're an old Eudora user with fond memories (or if you're amazingly still using Eudora 7) this is worth checking out. Let us know what you think.
The Penelope beta is a free download
